My husband thinks I'm fat!

So yesterday my husband and I got into a big fight. Long story short he ended up telling me I've gotten big. He says he doesn't care but I don't believe him. I was mortified because he knows it's a sensitive subject for me. Before we got married and had kids I was very active I was a dancer and did yoga, but I was never small I was around the 160-170 mark! Anyways both pregnancies were tough and I was put on bed rest early on so I gained a lot of weight. I also had both kids back to back, they are currently both under two. I've tried my best to exercise but having two csections back to back really put a strain on my body and limits what I can do. I've been eating healthy inspite of this and even use a calorie tracker, and I'm always eating under the calorie limit, so I don't think I'm over eating. I think it has to do with inactivity. I am a stay at home mom! I would love to go to the gym but I have seizures occasionally and refuse to drive, so getting to the gym can be tricky, especially since my husband works long days and I don't have anyone to really babysit. I tried at home work out DVDs but always get interrupted! My family has been supportive but his family has been making comments about my weight a lot too. I was finally starting to feel comfortable in my own skin. I'm afraid I will end up falling into my old ways as I've had a history of eating disorders! Please help :(
