Falling out of love

Me and my boyfriend have been together for three and a half years I love him but I’m not sure if I’m in love with him anymore I just feel nothing anymore I used to be crazy about him and chase him and always want to be with him now I don’t feel that way I wanna be around him but I can go places without him and be fine I wanna be with him and I want him in my life with me but I don’t know if it’s just a me problem we don’t argue or have any problems other than he feels like he can’t please me during sex but it’s because I never feel like having sex it feels like a chore when all I want to do is go to sleep I’ve only ever been able to get off by myself and we’ve tried toys and me showing him and it never works and he just gets upset because he thinks I won’t ever be pleased when I just can’t get off we had a very long conversation today about our relationship and he feels that I’m not in love with him I try to give him attention but I never feel like I’m enough he says he doesn’t want to be the only one that’s being pleased in our relationship
