Alright so here's the whole story. This HB8 I've known for awhile is in this relationship with a total loser (he's 23 and still has braces, your typical jealous type, controlling asshole). They fight all the time but because she still technically lives at home and hates her parents and that a majority of her friends moved out to LA about a year ago, she really has no options, so she still with him primarily to stay at his place and to chill with his group of AFC super needy puke worthy chumps.
I met her 3 years ago in a physics class and we hit it off, the problem was, I was in a committed relationship and she was single. Every time we hung out, I just acted like my typical confident self, and she ate it up. If even when i pushed her away all I had to do was start from the beginning and she would eat out of my hand.
I asked her to join my band a while back because she could sing. Along with practicing, we all started hanging out to get comfortable with each other. The rest of my band mates are total introverts or in relationships so naturally I became the fun, loud, and exciting alpha of the band and she dug it.
At this point my long term relationship ended, and i was ready to get my fuck on, no string attached.
Night after night we chilled, i ran my thing and i always got her to the point where she was just ready to give it up and she would pull away and say "i have a boyfriend"
So I did the usual, froze her out blah blah blah and she would be right back.
One night I raised sexual tension so damn high that she finally committed, and I thought i was in. Until the next morning....
Now her BF met us, and let's just say, we wasn't thrilled with me in the slightest. The only way it could be more obvious that he was threatened by me was if he flat out punched me, and i ate it up. So when ever we chilled and he didn't come by he would question the shit out of her. And apparently it got to the point where he grilled her and she gave up and told him that she was messing around with me.
The next day she was out of the band, I was being messaged by him saying that he could hire a lawyer to spin it into a sexual assault case (no he can't, but anyway) and that I wasn't allowed to talk to her or see her ever again.
So I said fine, no worries and i lost contact with her for a month.
Fast-forward to monday night, I get a random text out of the blue. It's her and she wants to meet up for drinks. Turns out she got into a massive fight with Captain Dickhead
I take her out, show her a great time, we have a few drinks, and then we get into my car and we fuck. And unlike the previous occasion, I gave her every trick in the book. I thought my car windows were going to shatter by how loud she was screaming. ( That's another thing, apparently this is her BF's second relationship in his life and he's terrible in bed)
I wait for the dreaded next day message from Captain Dickhead to see if she sold me out again, but to my surprise i get a text from her saying "Hey, I had fun last night, we'll keep this our secret" and a chain of other texts that insinuated how amazing of a night it was.
So now instead of a long winded field report, here's my question
I've never been someones booty call before and I don't know how to keep myself as priority #1 when shit goes sour again with Captain Dickhead. How do I go about this?
For further details, her BF checks her phone and Facebook, so calling or texting her readily isn't as much of an option.
I don't want a relationship with her (if her choice in relationships is Captain Dickhead and she wont leave him, then she's got shit to work out before I can even think about that)
So how do I keep that flame lit.?
