O_Troubles: That's him :-) Gosh, you are a good psychologist, it's exactly his behavior :-)
And yessss, he was VERY rude very many times... (why I got so pissed-off).

Not sure if I'm getting some scarcasom here? If I am then if your obviously mad "thats why you got so pissed off" then you shouldn't feel so bad durr, if I'm reading this wrong then OK glad ii could help..?

OK.

NOTHING you said in your rehash of the OP changes anything.

You seem to want advice that you aren't getting here, and that's unfortunate. My advice is exactly as it was before. I'm guessing most otheres will say the same, even after reading your "correction" of the OP.

You can twist, turn, and explain all you want.

There's a point where you CHOOSE to play the martyr or you CHOOSE to bear guilt for all in the world to see.

You made a bad choice. He made a bad choice. Its went even more badly due to circumstances that you were not in contol of.

We get it.

Stop trying to explain it more, thinking that we will suddenly see the truth. We see it. We did before.

You just don't accept the opinions you've been given. Your prerogative, I guess.

I'm done here. Just can't give more advice to someone who isn't going to listen. Waste of my time.

I agree I think what irks me especially is your title or this topic. How-can-i-make-my-teacher-forgive-me-for-my-betrayal. How many people have been posting to your topic we can't all be wrong or crazy, your not in the wrong here. You did not betray him mabie you think you did but considering what he did to you, and he didn't want the relationship and he was using you for lust, he betrayed you by not showing you respect. At this point he won't associate with you so don't irk it don't wave hello he feels betrayed good mabie he won't F*** with women and treat them like blow up dolls. Just move on you were right to do what you did he was completely wrong

What? You must have misunderstood me, guys! I did accept your opinions, I did agree with you, that it is simply a choice I make. On the other hand, not a single person knows about it except me and the department people. If I would have wanted to play a martyre, I probably would have told this to others, but I have only kept this for myself. This is an anonymous page, nobody knows me.

(But even if it's a matter of choice, sometimes, other people might chose to make fun of you, and do not regret that choice. In this sense, I must confess). I was simply impressed by that O-Troubles guessed on some things I didn't write... nothing else. No sarcasm, I promest, I simply got impressed... (I don't like making fun of people either.)

But I still don't like hurting people or harming their reputation. And even if I chose to move on, I will never be proud of myself that I had to "sell" someone, no matter what he did. But I will move on, I have no choice than just accept the situation and learn from it.
Sorry if I pissed you off.

I'm glad you can move on all I have to say in final is you have courage for doing what you did I admire you . I'm 17 and I picked up apparently on things you didn't say I'm young and not experenced if I could do that you must realise how stupid this professor is. Your smarter then him! I wish you all the best in your studies and all the courage in life to stay true to your values ButterflyLove

You didn't "sell" anybody. He did wrong. Wasn't the first time probably won't be the last. If he is not speaking to you, it is to your benefit.
You're so busy feeling guilty about betraying him, how would you have felt if he had messed with someone else, someone younger and really hurt them?
This clown needed to be stopped, you just put the process in motion. You probably helped others in the process.
