Daniella
So I had a feeling that my boyfriend was talking to other girls ... so I asked him if he was n he told me that he was seeing his ex girlfriend and she asked him to out with him... (n this had months ago n he just told a few day ago which I'm pissed) ... and so he kept asking if I really loved him or if I was playing with him n etc. Then he also told me that he has been talking to lots of girls on Facebook ... which so wer too far n well you know ... so I got mad at him so I broke up with him ... n now he is trying to come back to me and now i feel he is just trying to sweet talk to me to make me get back with him ... n idk what to do if any of you guy can help me .. what should I do ...
