I agree with SusanB!!! - Men DO NOT communicate like women do.
Men "make love" to show love - it's how they like to share love.
Women "make love" to be loved. Two very different meanings behind the same act, and yet, produces the same results!
It sounds to me like you are not ready to commit to weight loss. Believe me, when you're ready - you'll do it. And you can't do it for your husband, or even for your marriage - you have to do it for you, or it won't work.
If your husband doesn't love you because you haven't lost weight, then he is not worth having. You're better off alone, trust me.
But if he's fed up with other things (and this would be my guess) and it came out in anger about your weight, then your marriage isn't over.
You must get some professional counseling. You need a "referee" to discern each other's words until you can learn to do that for yourselves.
Save the marriage first - think about the weight loss second. That doesn't mean you have to do one & not the other - it just means that priorities should be set. This goes for your husband as much as yourself.
Things you can do together that would be helpful for both might include putting your 3 year old in a stroller & taking a long walk together. You can talk & walk, & that's good for the marriage & the weight.
You know - This is a good place for diet support - but I'm not sure if we have any marriage counselors here. Altho we probably do! And just remember - you are not alone. Plenty of us have been where you are standing right now. My first husband told me he would always love me BUT
"just don't ever get fat."

He was used to me being the itty bitty skinny minny I was during my late teens & early 20's. But in my mid-20's, out of college & just getting started in life... I started to put on weight. Not much (at first)... just about 10 or 15 pounds or so. But I lost them... plus another 20 when we divorced
Still - his words really stung me! - so I know how you feel. Please keep coming here & let us know how you're doing. It's amazing how people you've never met before can care so much!
