Weight Loss Sabotage

So, I think my husband is sabotaging me, and he is resentful that I think so. And I'm not really sure what to do about it.

He's constantly criticizing how I work out and trying to take control of my workouts. If I want to go for a walk, say around the neighborhood, he'll stop me and say "let me come with you." Okay, fine, but then that means we have to take DS4 with us, who doesn't walk very fast. Then he decides he doesn't like where I want to walk so he'll suggest we take a walk somewhere else that he does like. This usually means we have to drive and I have to now provide water and snacks for DS4. I don't eat the snacks, but the prep time, driving, etc., takes twice to three times as long as if I'd just gone for a walk around the neighborhood. When we do this we don't walk very fast so I'm not really burning any calories. It goes from being a workout to a nice evening stroll. It's relaxing but counter productive.

When I say I don't want to do that or suggest an alternative he'll turn his nose up and sometimes he'll simply leave me with DS4 and drive off by himself to go on the walk he wanted to. I'm then forced to either forget the walk or haul DS4 around in the wagon. I can do that, except that of course DS4 wants to get out of the wagon and explore and walk himself. He also likes to pull the wagon. I actually love doing that stuff with him, but when I'm tring to get exercise in it's counter productive.

I've tried joining several gyms. He hates gyms and thinks they're a waste of time and money. According to him I should just be able to ride my bike, go for a walk, etc., and get just as much or more exercise. Except that of course every time I try he either sabotages it or tries to take control of the outing. I also cannot complain about the gym at all, ever. If I have any complaints he instantly starts badgering me to quit. The last gym I went to, he act hurt and upset that I was going to work out and then would badger me about when I was going to be home. I always felt so pressured that eventually I gave it up.

I've recently joined a new gym that is close to our house. I've been going at night after I get done with work, dinner, dishes, and get DS4 to bed. So far DH has been great. He's been finishing up dishes and helping to get DS4 ready for bed. But just yesterday he invited someone over for dinner without asking me about it first. It was my workout day yesterday and he knew it.

I've tried talking to him about this but whenever I bring it up he gets really upset and stonewalls the conversation. He tells me on one hand that he wants me to be healthy and lose weight, but his actions are saying something altogether different to me.
