How to deal with a cg who isn't present

I have a cg, though he isn't present a lot and I feel like a lot of the time he only half pays attention to me. We have a flip dynamic, as he regressed too, and when he regressed I always give him my full attention and make sure he's doing well and being healthy but I don't really get thst in return. I have brought this up to him and he just says it's because he's tired and stuff but it kinda discourages me from taking care of him knowing that if I needed to be, he wouldn't do the same. Any ways I can try to fix this?? Do I js try to move on from it??
