Am I Overreacting?!

I'm starting to feel more and more unwanted by him. Part of me is feeling needy and part of me understands that he has his own life as well. Working a full time job as well and extra curriculars eats up a lot of his schedule. Not to mention we live 45 minutes apart currently. Lately I feel like I'm pressuring him just to have some conversation. We used to see each other all the time, despite the distance and now I see him once a week maybe. We don't even have sex really anymore. It's plumited from a few times a week on average to once or twice a month. I'm happy for all that is looking up for him but am I wrong for feeling like I'm being replaced by it all? I need some advice on how to handle this.
