I know a girl in this exact same situation. Not only is she in love with the bum, but she has a child with him. And after she knows for a fact that he love him some paynus, she has recently told me that they are going to get married. I was utterly disgusted and shocked. I don't care what anyone says, she is stoooooopid as hayle.
I mean, not only has this child found evidence on his computer of him looking at tranny men porn, and chatting it up with them, but his ex-girlfriend told her how he confessed his gayness and even let her do something to him with a big ol' dildo.
Anyway...there is a WHOLE LOT more to this story(you ladies would be shocked and disgusted), but, like I said, she said he is about to marry him. I have talked and talked and talked to this woman about hiv/aids, building her self-esteem, more fishes in the sea, being used...you name it. Still, she wants him. My husand and best friend hate that I have talked to her so much because they say she will always choose him and I am wasting my time. I have finally given up on her. I had to, stuff like this can weigh down your soul...even though it's not you, your situation.
OP:
If that girl doesn't want to leave that man, there is no evidence she can find and no advice that you could give that will make her leave. I learned a long time ago, some women, no matter what, will never let go....some of them are fortunate enough to have the man let go of them, first. The man will bounce when he is done dogging her out. The woman then screams - "how can you leave me?! After all I put up with/gone through with you??". Shoot, ain't the man fault they put up with bull and stayed where they truly were not wanted. And the sad thing is, even after the man leaves, that same disrespected woman will GLADLY take him back if he came crawling back...like I said, they never let go.
