Not sure if I'm still in love...

So I just moved in with my BF like 3 days ago, and before I even moved in with him I was hesitant. I am not sure if its commitment issues for me personally, or if I was resisting because I'm not actually in love with him. Some days I am in love with him and really appreciate things he does, and other days I can't stand him at all and seriously question why I'm even with him. Then I feel anxious and get frustrated with him super easy with everything he says or does or doesn't do!! I'm stressed out about it because I feel like I don't love him anymore, but it's a confusing feeling. Help!!
