It feels like he doesn't want to be with me

This morning he called me but sounded and acted like he didn't want to even talk. He hasn't checked up on me all day. I texted him earlier and thats the only reason we've talked. I asked if him and I were going to call because we didn't call the night before and we try to call every night and he was just like why wouldn't we... one minute he's cold and distant and the next he's like I love you. I don't understand what's going on. He's not one to open up but I can't keep having racing thoughts in my head. Do I ask him what's going on or just drop it? Am I being to emotionally attached? I've been hurt all day and he acts like he coukd care less, I just need someone to be here for me, ya know?
