Is the relationship dying or getting comfortable

Making it short, so hopefully don’t miss any key points.

Me(26F) and boyfriend (29M) have been together 6 months. He stays an hour away, but comes and sees me on the weekend, we spend about 24 hrs together in total IF THAT a week. The communication is at a LOW. The text back is SLOW. It was quick transition, he use to call me right when I got off work. I got off at 7, he would call me at 7:30 at the latest and this was about a month ago.

I have said when we first started dating I don’t like “comfortable” relationships. By that I mean when it dies down, no effort is given. He makes my effort low, because I am only matching his energy for what I feel I am given. He is very nonchalant, even though he does not agree. Everything is “WHATEVER, whatever you want to do” and I’m the complete opposite. And he is making to where I’m thinking of exploring my options, but I do like him. But he isn’t listening anymore. I’ve stopped the nagging, because I’m sick of hearing myself. We use to play games on our phones together, don’t do that now. I have to ask for him to play his turn, which feels like nagging. We do still go out on the weekends, do anything I want, but that’s the only plus side. We are suppose to have a 3 day trip together this weekend. But once the weekend is over it’s back to the same BS. I just feel like I’m not getting the same attention as before and therefore sounds like the interest is dropping
