I could do with some help with a girl I added on Facebook. She's pretty hot, about an 8 in looks. Seems really nice to talk to. The thing is she has a boyfriend, and he's a compete arsehole. She's actually engaged to him. When I added her we got talking, and she tells me how he cheated on her 3 weeks before, but she forgave him. She's bored of the relationship since all they ever do is the same thing - she goes to stop at his, they stay in, have some chinese food, and have sex. I asked her why she stays with him and she tells me that it's because there aren't that many guys queuing at the door for her. I say "well where is it? I'll be straight there ". She then gives me her number and tells me to text her.

She writes on my wall on Facebook a few weeks later asking if I've forgotten about her since we hadn't talked for a while, teases me saying I'm ignorant. I reply, then I don't get a reply back. Today I text her, asked her why she'd not answered me back on Facebook, teased her for being ignorant (as she did me too last week). She tells me it's because her boyfriend doesn't let her talk to other guys. I've pretty much just told her what I think, thet I don't know why she stays with him, that he's a controlling arsehole and that he's just scared she'll find someone better.

With other girls I'd usually use the straw man technique (for those of you who don't know this is just building him up and making him out to be a great boyfriend, then letting her attack him and think about all the bad things while you don't say anything to attack the guy) but how can I make a guy like that out to be a great boyfriend? I can't. So yeah, could do with some advice. Any other ways to BF destroy that work?
