Husband called me fat today!

I have been struggling with my weight most of my life but was doing well and feeling great about myself three years ago. Since then I had two children back to back and during the pregnancies I gained 40 and lost some but gained it all back. My husband and I have been together for seven years and we got together at my heaviest then and I lost a decent amount of weight and kept it off but after having my babies I just can't get back to it. He has been working out and eating healthy just in the past 3 months and now he criticizes me, he is overweight also and I'm very happy that he is feeling better about himself.   He leaves all day and I'm with our babies ( 23 months and 8 months) I love being with them and It would be nice to dedicate sometime to workout like he does. I bring it up to him like how can we work out a schedule so we both can take sometime working out. He always says idk and I can't do anything else I'm so busy. So today right when we woke up he said that I really needed to do something about losing weight its not ok being obese like you are! And goes on to say " no wonder I don't feel like being all romantic to you" " you need to lose weight because you're unhappy and that's because you're fat." I know it's ok to have constructive criticism but DAMN! I'm very hurt by the way he said things and I don't know how to feel now? I just kept quiet and a very serious face on but as soon as he left I cried. I'm wanting to lose weight I just can't get out of a funk because he is putting me down and I feel worthless because if he my husband isn't into me and building me up then why try. I don't want to do it for him to tell me I told you so and then become all romantic because all I'll be thinking is F-YOU! How should I handle this? What should I say to him? Please no negativity I get enough of that at home✌🏻️
