What is wrong with him? He wakes you up in the middle of the night to get some sex from you? Sure he did some stuff too but it sounds like his expectation was that you have to do the same even though it’s middle of the night. And you are woken up. What’s his deal? He sounds immature.

Do you think you consume alcohol to help you deal with his inconsistent behaviors and all this drama? It’s not uncommon. It sounds stressful

I don’t think you not trusting him is just your issue. Whenever I didn't trust someone, I was always right about them: they weren’t trustworthy. I have no trust issues trusting trustworthy people. I suspect you’d trust trustworthy people too. I don’t think he’ll cheat but he doesn’t sound like a person you can rely on in life with 100% certainty. That’s maybe why your gut feelings tell you not to trust him
