I have been on both sides of this, so will give you my personal experience. I used to virtually do and say the same to an ex however I had fallen out of love with him and loved him like a brother or best friend, I wasn’t in love with him anymore. Whenever he asked why, I told him I was tired, worn out from the kids or other excuses etc, I just wasn’t brave enough to tell him the truth. I did when I realised I was being unfair, tell him the truth about six months later.
I eventually married someone else and we have a great marriage however he has adhd and that brings about it’s own problems with emotions/relationships and also the fact that we have mismatched sex drives, funnily enough I have the higher sex drive now and only now do I realise it’s not always down to having a high/low drive, it’s about who you’re with, it was for me anyway.
My point being I have done the talking, initiating, massage, etc etc and it’s not about that, if the feelings aren’t there, they are not there for a reason and I’m not saying it’s because she doesn’t love you/fancy you, I’m saying as an example, just because you haven’t done the dishes doesn’t make her not want to have sex with you, however it could be the resentment that’s built up from that, that’s stopping her.
Try couples counselling, we did and we went not to focus on the actual act of sex but to communicate about it, we still have different sex drives but we are on the same page now.
