Attraction to husband is lacking or is it?


I’ve been with my husband for 12 years. Like most relationships we’ve been through a lot together. I’ve gained a lot of weight and had breast reduction surgery 3 years ago. I lost most of the feeling in my chest and have horrible scars and hence a lot of my sexual pleasure is now gone and I hate how my chest now looks. I have no desire for sex but know it hurts my husband and strains our relationship. What would a healthy model look like? Any other advice on how to feel more attractive to him and to myself? Thank you
