I fb messaged my ex boyfriend's new girlfriend...?

What you did was really out of line and so very immature. She did not initiate contact with you, and doesn't have any desire to be caught up in your drama. What happened between you and your ex is between you two. She probably feels like he was justified in dumping you over the boob incident. I don't know very many guys who would allow that foolishness. The fact that you are now contacting his new gf only proves that you are not right in the head. You are lashing out, venting, and it is all only your problem you are now projecting onto others and ramming down their throats. It makes you look crazy and mentally unstable. I would ignore it too. She's probably irritated at first, then got a good laugh out of it. She's too smart to be drug down into the cesspool of hatemail exchanges with you. She interprets all this as jealousy towards her, you are the 'ex' after all. It only makes her feel superior to you in most every way. Stop making a fool of yourself.
