Easy to say this, but maybe hard to do.... IMO, you need to be strong, whether you give him physical affection or not. You being in charge is important in the sense that you can give him what he wants or you can withhold it, but you are holding the reigns. I don't know what choice is better, as I have heard it both ways.... be his girlfriend, act like his girlfriend and lover, or withhold it, be nice to him, but no physical!
Either way, you can be strong, and in control. I have not read your whole story yet, but I will have to. Sorry for your sitch!!! Happy 4th!!!!
