I have been in 2 past relationships where I have been cheated on and I met this girl who was so nice to and new of what I went o and promise not to put me through this angain. Been together for a year and she did the same thing.really hurt me. Now she wants to fix things but its kind of hard.I really do love her but she broke her promise. Took some space and met someone else who is so sweet and different. But its always like that at the start. I really do love this new girl feels so different but the other won't let go and part of me won't either. What should I do.
