Feeling low about my body😥😑

I've been with my boyfriend for a yr and we had sex a lot in the beginning but now I'm lucky If I get it once a week .. He's in to big girls I was 220 when we got together and I've lost a lot since then I'm not 160 and I feel like I'm not sexy to him and today when he was at work I took this pic for him and sent it to him and all I got back was (OK).... Really felling bad about my body 😥😥
