is this falling out of love

Tia

I been with my partner for five years, my first ever boyfriend and I have two children with him. We have our good days and bad days but lately he's been so intimate and wanting sex so much but I don't feel it for him, I feel awquard and I dread going to bed because I know he will try. Sometimes he comes out from bed to loungeroom to try and I'm like

He isn't funny any more and never laughs at things he just gets angry at everything and he doesn't take care of him self as in he never wears nice clothes out he just wears he's work clothes and he doesn't want to cut he's hair or shave he's beard.. I feel like I'm drifting away from who I used to be so madly in love with. I have spoken to him about these things but he doesn't care, says he like he's hair and beard long and he couldn't be botherd dressing nicely. Just lost and venting
