Fiancé isn’t interested in me anymore

Hi so I’ve been with my fiancé for 7 years but I don’t feel like he fancies me anymore I’ve spoken to him about and all I get is yea he does and I’ve looking for an argument when I’m literally trying to just talk 🤷🏻‍♀️ anyway we booked a weekend away together and we obvs had lots of sex but I was the one who had to start it every time also I got sexy underwear and it was like he would hardly look at me 😭 he said wit woo like nah 🤢 I’ve tried to spice things up I sent him dirty videos today while he was at work and he replied with well you clearly aren’t very busy like I just want to feel wanted sexually he always says he loves me but sexually I get nothing it’s really affecting my confidence as well he’s also the only man I’ve ever kissed or slept with,I don’t know what else to do x
