Relationship is draining me

Hi I am in a 2+ relationship and I started dating him in my 2nd year of university. I have moved back home as I’ve graduated. We live 3 hours away from each other. I love him a lot but I feel so drained. I have to beg him for basic things such as just sending a small message when he’s out with his friends, personally I don’t think it’s a big ask. I keep having to ask him or prod him because I do care about his safety. I had to prod him about unfollowing girls on his ig as he followed lots. It’s not that I get jealous, I just think it’s respectful to do so. Friends are fine but not girls you knew from 10 years ago and don’t even speak to anymore. Anyways last year, something happened between us that made me completely lose my trust in him. And every time I’m alone with my thoughts, I end up thinking about it and it makes me feel so upset. I know he loves me a lot and I do too but I don’t know if it’s enough for me to stay. He works a lot and he can’t text me much and I truly understand that and I try to support him as best as I can. I just wanted to share my feelings with random strangers so I feel lighter and may gain different perspectives. Ps we have really good communication and I do tell him how I feel and he tries to be better and so do I. But I can’t help how I feel.
