Not like we use to be

My boyfriend left for a trip for a few days and just got back today. He didn’t even seem excited to see me. Didn’t hug or kiss me. Ask how I was or what I did or anything. He just got home and he left with his friend.

We text while he was on his trip. And it was decently normal I guess. He didn’t call me babe or say anything cute.

I felt so relaxed while he was gone. No anxiety, no stress, idk what it is. I love him and all but I just feel unloved and sad that things haven’t been the same as they use to be.

Thoughts/advice?
