Secret Boyfriend Guilt?

I’ve been with my boyfriend for about a year and a half and I don’t know what to do with our relationship. We are both in our twenties and are currently living together while I attend grad school and he works. My parents don’t know he’s staying in my apartment because I know I would get in a lot of trouble if they knew (they are pretty religious and traditional Mexicans). My parents don’t really like him cuz he doesn’t look like “my type” and they think I can do better. They think he lives in another state. He’s my first real boyfriend and the only person I’ve had sex with. Lately I’ve been getting vibes of us getting too comfortable around each other and spending too much time together. He moved across country to be with me, so I feel some pressure that I’m the only friend he has in our new state. It wasn’t our plan to live together but he’s been staying in my apartment for a few months now and we’ve both gotten pretty comfortable. He’s wonderful and very funny and super smart and very helpful and loyal but I often get annoyed by how different we can be in our styles of things. In public, it’s hard to introduce him to my new friends because his styles of humor and communication and small talk are very awkward to some people. In private, I’m often reminding him that he is belittling me or not giving me enough affection. I’m not getting orgasms anymore. Am I over him? I don’t want to be but I also feel like the guilt from keeping him from my family distances me from him. But the thought of breaking his heart crushes me. I haven’t seen him while Ive been on winter break for a month and every day is easier to stop missing him. Idk where to go from here and I could use some pointers if anyone wants to give any advice.
