So angry at husband and cannot let it go

That isn't a reason. Your marriage is dead at best, actually it's toxic and unhealthy. So four people have to endure a miserable, unhappy existence (including those two children)! YA both BU inflicting this on yourselves, each other and your children.

YABU for still being married to him.

It’s OK to get divorced. It isn’t really a marriage is it, it’s just a horrible situation neither of you have yet found the courage to leave?
Would you be hurt or angry if he said he was off, or actually would you be relieved? Presumably if he keeled over you wouldn’t be grieving on your own behalf for very long?

Would either of you be interested in couples therapy?

Does he seem gay? If he is only attracted to young or very slim women then gay isn't what I'd be thinking...

Idk what his real issue but it's clearly not your weight. Size 12 is the slimmest many women have ever been. He's using that as an easy excuse because many women are sensitive about their weight and it fits the cliché, horrid narrative of 'she put on weight and the sex went out of our marriage'. Since he's heavy himself it's a double standard anyway, and a loving man wouldn't have spoken to you this way in the first place.
He's obviously not being honest, and it sounds like time to get your ducks in a row and plan to move on.

I think you posted another almost identical thread a few days ago OP. Really, as you were told then, the only solution is to leave. Your poor children.

Plenty of women successfully rear children alone after leaving deeply unhappy marriages.

You're using that as an excuse to carry on with the status quo.

26 years!?!?! What a lot of time you've wasted!

He's clearly into teenagers whether they're male or female.

LEAVE.

Because we have two children together.
Show quote history
I'm going to assume you're from somewhere where separation and divorce are frowned upon, because at least here in the UK, plenty of people separate from their spouses, despite having children together.
Whatever culture you're from where having kids means you're expected to stay in an abusive marriage, nevertheless you need to figure out how to get away from him. Imagine spending the rest of your life with this vile abusive creep.”

This. Your DH sounds awful. It’s also very damaging for children to grow up with parents who have contempt for each other.

So you say he only looks at women if they are very young (teen) and he’s only interested in you if you are very small physically…. that doesn’t sound like he’s attracted to men it sounds like something else.. have you checked his computers/phone/browsing history?

And?

You sound entirely focused on him. What he thinks, how he reacts, how much you loathe him, how much he has betrayed you. I can’t see you leaving while your thinking is so bound up with him. Please have some therapy and think about what you actually want in life, leaving him aside. What size do you think you looked better at? What do you like to do? Do you have work ambitions, travel, pleasures? Do you like being muscular, curvy, thinner? There are happy and companionate sexless marriages out there, but this toxic warring landscape sounds hellish and at the moment even if you left him I think you could risk being one of those exes who keeps talking shit about their ex-spouse for decades because you’ve never detached and moved on.

Well you are the one putting up with this for a lame reason OP.

Bitterness is pointless. Grow a set and make plans that don't include him instead of toxifying your own environment and that of your kids.

One of you has to be the actual adult and it's clearly not going to be him.

That's a bit of a jump, op hasn't mentioned any risk to her children. A man can be an abusive husband without being a pedophile.

This was my first thought too. Sorry op.

Her love is not based on size, but I'd imagine being assaulted by him does feature, FFS.

As PP said, my money is on porn addict and he's projecting whatever his viewing preference is onto you.

I don't blame you for being repulsed by this guy, he is repulsive. You talk about a size 12 being large, but come on OP, it's hardly mobility scooter territory.

I apologised so move on and stop trying to make this about you and whatever you presume to be witty and clever.

Do you always try to make everything about you?

I’m just baffled you wasted 26 years with this loser already and good sex wasn’t even on the table.

Please leave this walking 4chan ad 😭

You can leave.

You will still have 2 children together.

By leaving and co-parenting well, you could give both you, him and the kids a happier life.

You sound completely unhappy. Anger / resentment in a marriage never end well.

Hmmm, would you say your figure becomes less typically adult female, and more "boyish" at your lower weights OP?
I'd be interested in his online activities.
Regardless, he is an abusive man and you are wasting your life with him. Get out and create a happy home for your children.

Your kids deserve to see you happy, as do you.

Are you family and friends very anti-divorce? (Reasons of religion, culture, just old fashioned.)

You have wasted years of your life in this relationship that doesn’t work, do not waste any more time.

Life is too short to spend it being unhappy.

After 27 years together, your kids must be grown up? It’s time to focus on yourself now. They will know your marriage is unhappy and might be relieved if you split up. Think about the years ahead and plan for freedom and a happier life.
