I see, and agree with what you're saying GB. Although we never had what one would term a relationship, and I do blame Fran for quite obviously leading me on, I also realise that it was totally blind of me not to be able to see what she was doing, and even now I feel an idiot (it's the only way the idiot can get physical human contact)
I blame her, sure, but I also blame me, and if anyone says later (as many did) "Jesus man couldn't you see she was playing you for a fool?" I hang my head and say yeah I should have seen it. Much as I hate her now, and blame her, I don't blame her solely. You need to take responsibility for your bad decisions, choices and judgements.
