Why do you want to be with a guy you don’t trust, who isn’t at home at 4am when you drive by to check up on him?
He doesn’t want to be in a relationship with you. I’m sorry, but you can’t change the way other people feel about you. I mean, what is the appeal, the sex? It’s too late, he doesn’t want to have sex with you anymore.
I’m sorry things did not work out the way you want. Sometimes that happens. The best thing to do at this point is to move on with dignity. Stop contacting him. Therapy.
