Gunner is still in love with theo, he's not treating theo like a sextoy. He thinks theo still love him despite everything he had done to him, so he keep on hoping. And we'll, sex is what he thinks make it fair. And he at the end of the day is really a dickhead.
It's called obsession and you don't treat someone you love like that, he really is hopeless Theo gave him so many chances but he didn't change, why Theo is the only person who has to accept all of his bullshit in their rs? and I hate it when the ex bf using sex as a way to save their fucked up relationship it was actually disgusting I almost thought their past story was cute but gunner ruined it
Theo was right about gunner only treats him like a sextoy, may be they were in love back then but not anymore, I'm glad mc used some brain this time, I almost dropped it cuz I thought Theo left some feeling for that dickhead
