Idk what to do

So my boyfriend and I have been dating for 6 months. We see each other almost everyday. We do fight a lot but end up making up. I was gunna break up with him but then I started to remember all the good times we had and why we started dating. Also he wants to kiss me every second and say I love you every second but I don't, it's a little annoying to me. I don't feel like having sex with him anymore. Is it cause we see each other day? Should we spend less time together?
