I don't know your back story belle, I don't know "why" you choose crap men
(I do know you are rather fiesty, funny and fab, from other threads I've seen you on, though...)
I cannot understand why you want this man though, other than the emotional tie because he is your dd's father (strong, of course, but IMO not strong enough to put up with shit)
you acknowledge is is shagging his wife, you know of one other (I suggest if you know of one, there are lots more...)
he appears to be a serial shagger, and a commitment-phobe
ok, ask him to commit to you, maybe he will
but do you want to be where his wife is now, in 5 years time
if he wanted you, he would have chosen you a long time ago
you are turning a blind eye to the fact that he is a happy philanderer...he won't change for you, sorry
and if you have tolerated it so far, he obviously thinks you will continue to do so and are just being "difficult" now you say you don't want to (but he will assume, it's just temporary and normal service will soon be resumed...)
he will bide his time, get you sweet again with empty promises, then fuck you around
I don't care how goodlooking he is, although he probably does, I could not spend my life scanning the room at a party for any "competition"
I lived that once, and would never do it again
if I am way off, please feel free to tell me to go fuck myself
