Am I the problem?

My boyfriend and I have been together for some time now. As of late, he’s been doing some things that have been causing me to feel rather insecure and skeptical.

I have a bit of a drive to and from work. I like to call him on the way home from work. As of late, he rarely answers my calls. He calls me back an hour later once he feels as if I’ve made it home. I get that things can come up, you can get busy, but he doesn’t answer to tell me that he will call me back or anything.

My work schedule doesn’t make seeing each other the easiest. I work most weekends. But when I finally get the weekend off.... he chooses to play the game with his friends until 11 and then wants to come over on Friday. By then I’m tired after a long work day. Mind you, we don’t see each other during the week often, so he has all week to play games with his friends.

Lastly, at one point, he couldn’t keep his hands off me. Now, I feel as though, I have to ask for sex. And whenever I do, 8/10 he says he’s tired. Or gives me lazy sex. This is ruining my confidence.

We were supposed to hang out with his friends this weekend. He was super excited about it earlier in the week. As of last night, he’s no longer interested in going. Alleging that he doesn’t want to be around certain people. But he hung out with this same crowd less than a month ago (I couldn’t attend this night)? Could it be that he’s done something and worried that his friends will drunkenly spill the beans?

Am I tripping? Insecure? He swears that it’s nothing going on.... things just aren’t adding up.
