<human>: Condense the text into a few key points

I know this is a menial concern compared to many here, but I do appreciate any advice. 

We've been together for about 8 months now and it has been a wonderful relationship. Lately, though, there have been a few little things that concern me. For instance, him texting less and the replies being one-worded or spread out, or not calling me "babe" as much, just little things that were so commonplace that it makes a difference when they change. When we are together in person, everything seems the same, he's still affectionate and we are still together for the same amount of time as usual, but I can't help but pick up on those changes.

Forgive me for making a big deal out of a small issue, but I have had awful experiences in my previous relationships so my confidence level when it comes to them is a bit shot. He's the first relationship I've been in where I've been genuinely happy and comfortable and I just don't want to mess it up.
<bot>: My (22/F) SO (26/M) of 8 months has been acting a little differently lately (not texting as much, etc), is he losing interest or just getting more comfortable?
