He didn't say I love you

I don't know why I noticed, but he didn't say I love you today. I felt awkward being around him, maybe because our relationship is changing. First of all, I've moved far away, and he can't spend nights with me because of my job. And second of all, he has his weekends tied up with the show. Then there was the episode on Saturday when I drank too much. Maybe he's being cautious on how he proceeds from now on. I feel like our relationship is different, but not the good way, like more comfortable. In fact, I've felt less comfortable around him lately.I know it's all in my head, and I wish I didn't do that to myself. I'm trying to find faults where there are none, so that I see it coming when it doesn't work out.
