Tyler's got it right. John, you need to learn to take fucking charge, man. From what I can construe from your post, you were seriously dependant on this woman and you should never be dependant on anyone. You still let others' perceptions determine your own perception of yourself and if you live your life like that, you're guaranteed to keep walking into the same trap. What the woman did to you is pretty disgusting, but it wouldn't have happened, she wouldn't have had that kind of power, if you didn't give her that power. Because you did - by being dependant on her and attaching yourself far too soon.
Next time a woman hugs you and kisses you and tells you she loves you, you need to stop right there and ask yourself, "is this normal? Is this the way a sane or caring person acts?" If the answer is no, keep that person at arm's length until you're sure she's healthy for you. People will and do fake these feelings for their own gain, and you need to learn to tell the difference. You are so in need of love, you'll cling to anyone who shows interest, and that is your major malfunction, numbnuts!
There's loads of good girls out there, but you'll never attract them with your neediness and self-pity. Stand up, clear your head, and next time, don't let yourself get punched to the mat so easily.
