Bf isn’t attracted to me anymore

Me and my bf have been together for two years and we use to have sex all the time multiple times a day and we use to try for a kid but for the past year he doesn’t have sex with me anymore it’s been 6 months since the last time I had sex and I feel like I’m not shit to him and I’ve accepted that I probably will never have kids due to this and I ever time I ask him why we don’t anymore his answer is always I just don’t want to should I feel some type of way about this or does anyone see where he is coming from and I shouldn’t let it bother me anymore?
