what you did is very bad. She was your friend, if she was cheating on her baby daddy, what you should have done is to talk to her and make sure she quit cheating on him, or you stop being friends with her and her baby daddy. But no, you didnt do that, you went to tell her baby daddy that she was cheating on him, there must be a reason why you did that. I know that the reason was coz you want to snatch him from her, but guess what, karma is a bitch. If that man could listen to a gossip from you and leave his baby mama, and worse of all , he had the guts to date you, then he has a big problem. What kind of a man will be comfortable dating his baby mama girlfriend, if not that the man has issues on his own. Watch it, that man will never trust and respect you, he will always see you as a snitch and he when he sees a decent girl that he truely loves, stories will come up...... am sure you know what i mean... he will quit the realtionship he is having with you after cheating on you. Karma is a very heartless bitch.
just what I tut too....you couldnt have said it any better. The truth is that the part of my heart that wanted to advise you just shut down cos you said you betrayed your own friend....honey there are so many ways you can help her stop cheating rather than doing what you did..
PS..this is a healthy criticism!
