I'm going to sleep at my guy friend's house even though my boyfriend doesn't want me to
Do you have a reason for sleeping there?
Not really, I have the feelings and I don't care about my relationship.
He shouldn't dictate where you sleep. But it sounds more like you aren't happy with your boyfriend regardless.
He is not a good guy anyways, I'll sleep wherever I want and talk buckets about him.
It sounds like you don't care much for your boyfriend, and if so you should maybe just leave the relationship and sleep wherever you want.
