Separate? Stay?

I don't know what to really do.. my S/O and I have been on a rocky road and feels like we're drifting apart. He says he still really likes me/into me and still wants to be with me but lately it just hasn't felt the same. He's been really busy with finishing college and getting his life started so we don't really talk as much anymore. I've tried to talk to him about how I've felt lately and it would seem like he just wasn't interested in really talking about it.

Right now we're kinda taking some time apart and the more I keep thinking about it. I'm just torn between whether it would just be best for us to separate (which he doesn't want) or try to keep it going..
