Boyfriend troubles

Me and my boyfriend have been dating for a month. From the start we argue and fight but we get over a make up. But at the moment I feel like we are drifting apart or losing feeling. I don't know what's happening. He's also finished school this week while I'm still in school. He apologied for pushing me away lately but it doesn't feel like it's enough he blamed it on alcohol and school. I feels like I'm going to lose him
