Is it over or am I overthinking?

We've been together officially for4 years. Lately he's been really distant. I asked him about it he said it's personal and he wasn't ready to tell me about it. He said it's not about me and it's nothing bad just personal so I tried to just back off. Then he started getting mad at everything I say or do. He spends hours sitting in the car smoking while I'm in our bed alone. We don't have sex haven't in months. He keeps his phone on silent and I don't know his password but he knows mine. He's been helping his cousin this past week she's getting the last minute things for her wedding this weekend. But he barely talks to me since he's been over there. Whenever I do call it seems like I'm being rushed off the phone. But he still tells me he loves me daily. And when he was home he'd give me kisses if hed come in the room and I was sleeping. I probably sound dumb but I love him and I guess I'm just hoping I'm wrong and everything is fine between us.
