Relationship question!

Hey ladies so I have a question about my relationship with my man. We have been dating for almost 5 months and the last month and a half has been so different, he has been more distant and I feel like he doesn't put much effort into the relationship. He lives 45 min away we both have full time jobs and he's in school so both very busy and I'm almost always the one driving down there, asking to hang out saying I miss him and love him first and he has stopped calling me beautiful and texting me in the morning or if he even texts it's very brief. He never calls me anymore and says it's annoying when I call him without asking him before or leaving a VM telling him I just love him or miss him. He tells me he loves me and cares when I bring something up and I've never been very aggressive with what I want or need in a relationship but I want to feel loved and beautiful and cared for, I'm thinking I should tell him, how do I bring it up with out it spiraling downward into an argument with him thinking I'm telling him all these things he's doing wrong? I just don't know how to get my needs clearly explained with out it seeming like I'm "blaming" him I guess if that makes any sense. Anywayys I'd love some feedback. Thanks!!! 💗
