I started thinking about how my FP (also my significant other) used to call me almost every day and invite me over most nights. He would make an effort to cuddle with me frequently and he would video chat with me if we weren't able to see each other for a few days. He seemed generally happy and we had sex frequently.

It's been almost 3 years now and he keeps about half his clothes at my place, has a key, and keeps all his toiletries there so he basically lives with me part time, almost full time. He doesn't call me anymore, I always call him. He doesn't video chat me if we're apart for a few days. He basically puts in effort to give me attention every once in awhile, but it's not consistent like it used to be and our sex life has dwindled to almost nothing.

I understand that logically, people get comfortable together and stop putting in as much effort as they had to in the beginning of their relationships (whether it be friendships or romantic). I was mildly annoyed about our dwindling sex life, but I understand that fades naturally as well, even if I wish it didn't. I started reminiscing this morning about how things used to be and it sent me into a total panic. 

Has anyone else managed to upset themselves just by thinking about how things used to be?
