I have no idea what you did wrong/regret. Can you explain it a bit better? start at when the problem began and walk us through and then we can try and help. As of now, I don't understand the problem.
I regret that I accept my friend's love confession. I thought he's the right one for me, but apparently he is not. He's not acting like himself since he dated me. Sorry for not being clear...
If thats how you feel, talk to him about it. It might lead to a break up but it's bettter to get your opintion out. Don't always hide behind a mask to block your true emotions. Iif you guys do break up, then crap happens. I can't tell the aftermath since all humans are different and stuf.
