Ladies what would you do and how would you respond if your husband sent you this this morning?

A little background. .. we have been together for seven years at first our sex life was great until we had our daughter (she is five now) and our sex life slowly started to pick back up after she was born. However there was a time of cheating on his part once not long after that. Fast forward to now. I thought we was doing good our relationship has gotten better we communicate better and everything. He seemed happy as well as i. Well guess I was wrong as he sent me this this morning. . Keep in mind that my periods are super long and super heavy so we don't have sex while it's here which is a couple weeks at best each time. The others times he is usually to tired if I try and start something or just wants some head. And he never wants to start it besides when I'm sick or my period is here. We both love each other but idk anymore... I give him head usually when he asks for it especially if I know I can't actually do it and when we do have sex it's usually the same old same old which I have tried spicing it up which failed miserably. I'm starting to think he isn't attracted to me physically anymore as when we got together I was not super skinny but skinny and since our daughter was born the bc made me gain weight and it's been hard to lose it and a year ago was told I have pcos. And he always talks about he misses how I used to be sometimes. I've tried and still trying to lose weight which seems hopeless. Idk what would you do? I crop it so no one can see his pic or phone number.

UPDATE :::: I finally got him to talk to me about what the issues were. And I was right its bc of my weight :( . When we got together I was skinny and pretty and after I had my daughter three months after I got the m irena birth control and it made me gain weight like crazy. After three years it started causing me to have pain so I had it removed and bc we decided to ttc number two. Well a year after having it removed I was diagnosed with pcos so now it even harder to lose weight. But he said it's hard seeing the person you love go from being hot and skinny to still hot but not so much skinny. Says we used to have fun in bed and this and that but bc my weight we can't do all the things we used to do. And that's what made him say he wanted to stray away bc all he sees is skinny hot girls and he used to have that but not anymore. He asked how we can fix that I told him I'd work harder to try and lose weight and if I couldn't then I'm sorry. I'm glad he was honest with me and we agree to work on our problems before he went and cheated. But Damn this hurt my feelings big time :( .. well figured I'd give an update.
