What you say is true.. but If he cant forget your past, theres no point u still hang on, right? ( this is when u think that having intercourse with others is alright, so u both just move on)

Things like this already happen not only 1 time but 2. It needs time for him to forget n accept it.
I guess you shud think about yourself too.
If you really like this guy, i suggest that you commit to the fullest to this guy only n not thinking about others anymore! ( this is when u think that youll change n make him believe you that he is the only guy for you)

Also, what if you break up again, will the next guy treat you the same or will u haunt the next guy by saying u had it 3 times b4 him? ( this is when your scared that no1 wants you or similar situation that will happen to your next bf afta this)

Decision is yours. What you think is right then just do it, if not ull regret in your life. We are here just giving you some of our views n opinions.

I agree with you too

Easily forgive, but its hard to forget.
I guess even you yourself also cant forget right suzanne2196.
