Interesting. Amongst the 209 of comments in the forum, there are quite a handful og them are damn stupid comments (non-related comments and takes up & >10% of the 209), mostly are commenting on those little stuffs such as typo error (which took up & >50% of the 209), a few negative comments on bf, a few negative comments on that girl and a few telling that girl's bf (master of the forum) to pay more attention to her and also that he's bo liao.
You know, this shows that this whole thing is so plain stupid and meaningless.

To Miss Tan's BF:

In my opinion, all parties have faults, no one is right. Our actions (regardless of he/she protects him/her) only proves that we care for them (regardless of him/her). Like you had mentioned in the forum that you believe whatever she said, it applies for me as well, I believe what he says. After all, without the basic trust, then why get into relationship in the first place?


I must make clear of myself that I DID NOT approve Koen's action (the sms part). Upon seeing it (your gf's blog without those pics then), I confronted him (it was all before the blog-blog insult stuffs). He gave me his reason which I deem reasonable that I can't find any reason to not trust and believe him. During the period of blog-blog insulting, I even discussed with him about it, and even drawn up a deal with each other. 
All the while, I DO NOT approve my bf (not only him, it includes my ex who is my then bf) to be in contact with any of his ex, because I know that one day, such misunderstandings between ex-gf/ bf will happen. When I realized long ago that Koen is in contact with his ex, I had warned him. but that is HIS personal choice, I can only advise, I am NOT a control freak. (I hope this answers your questions)
For now, he had learnt his lesson, but because of what had happened, he and the ex can never be friends again, as the relationship is strained, which is probably the best for both parties.


However, what about YOUR gf? You should have known even earlier than me that she was insulting Koen every time. So why didn't you talked to her out of it? Yes, it is her choice to whether listen to you or not, but if you did try to talk to her about it, why did her insults got worse each time?


You mentioned that I had too much assumptions, but HELLO, your gf had as many assumptions as well. This is about girls. Otherwise, why would people say that girls are sensitive? Reason being we assumed and thinks that the assumption we made is true. 
Also, you mentioned that Koen could have kept a distance from her, but he treat her as a friend, and thought that she had also treat him as a friend whom he can talk to about anything, which turned out that he was wrong about her! It was a grave mistake which Koen had regretted greatly for believing and treating her as a friend.
As for the HWZ forum, can you please open your eyes big and see properly? It is so obvious that many are against his typo error rather than what he did. I am lazy to retype all the figures, neither do I have the time to actually categories them and give you the exact numbers, please kindly refer to the top for the estimated figures, thank you.


One more thing, I did stand in your gf's view. If I receive a guy's friend's sending me that msg, I will not do anything about it such as confronting or even did what your gf did, and ignore him. Do think about it, think what will you do if you were her, DON'T be bais. 
In case you don't know, I even had a similar experience, it's a true experience. There was once, I receive a msg from a guy friend (whom I had known for about 5 years then, when he sent the msg and I really treat him as a friend) actually sent me a consider as intimate msg, and my reaction was: Stop replying his msg. 
Yes, like Koen, he is quite open minded, but I am not as open minded (probably your gf as well) so I cannot really accept that kind of msg, but I know him, I know that he is just being friendly thus did not confronted him, that is why he is still a friend of mine and a fairly good friend. (Btw, to date, we're almost 8 years of friends)
What your gf did by continuing to reply him, she's only trying to tell Koen that "it is ok, I can accept that", and thus inviting trouble, which lead to all these situations. (I hope this answers your question as well.)


So, who in the end, can you actually blame? I can't say that he is right, neither can I say that she is right as well, because BOTH have faults! You can say that Koen could have kept distance from her, and all these would not have happened, but I can also say that Miss Tan could have not continued the msg until she's that unhappy and these would not have happened. Can you see the point now?


Lastly, right from the start, I am not siding anyone. I am just very unhappy with the way your gf insult him for all these years. Get it? I DID NOT insult your GF because of THE SMS! (you all have always assumed that I am insulting her because of the SMS the bf had sent and siding my bf's wrongdoing, BUT I AM NOT!) I do not want Miss Tan to saying that I'm contradicting (as though she is not contradicting like that), so I have to EMPHASIZE that, I believe Koen for the reason he gave me, but, he IS still in the WRONG, because Miss Tan cannot accept this behavior.


But of cos, it is up to you whether you can take in whatever I say. However, I have to EMPHASIZE that I am NEVER bias, I never tolerate any wrongdoings of my bf., as even for a very small problem, I will confront him.


I will appreciate that you and your gf will remove those screenshots/ pics from HWZ/ blog, as it is very disrespectful as well as over doing it. And in case you did not read properly, I need you to take note that, I AM NOT BIAS TO MY BF and I AM ONLY UNHAPPY WITH THE PART OF INSULTS YOUR GF MADE!


To Miss Tan's FRIEND:


Please do not blindly make comments in her tag board. For goodness sake! Everything I posted in my blog are my OWN OPINIONS! So please take back your words for saying that I do not have backbone. You're being very rude. 
For every word I typed, I think before I typed it. I do not blindly believe everything that bf said, I make sure that what he said sounds reasonable to me, I analyse his words before I deem that it is reasonable. 
It is so unfair of you to say that I merely believe whatever he said. This is so insulting to me. 
And lastly, I admit that I can be contented very easily, I had always been since young, and that is one of my good point.
