AIBU to be hurt by my husbands actions even though his son is sick?

There is no version of this where you are being selfish OP. I wouldn’t wish a sick child on anyone, and I have some sympathy and empathy for him on that count but that isn’t license to cheat on you. You deserve better…

Using his sick child is the lowest of the low. Take your life back and find someone who respects you x

Utterly sick. Men will use any excuse for an extra shag won't they.

Oh my, no way are you being selfish. He's the selfish one.
Yes, he's going through a terrible nightmare at the moment but he didn't need to cheat. It truly isn't a reason, there is no reason.
Am so very sorry. One thing, at least he was finally honest and you can make you choices based on that.

He has slept with his ex twice because their child is sick.

They are clearly getting very very close and old feelings are there a mistake (not cheating) happens once you don’t do it again that’s an active choice to keep putting yourself in that situation.

Don’t waste your time with this man. Leave and to hell with that anyone thinks.

They will sleep together some more and then either end up back together or separate but it’s not your mess

Your husband slept with his ex wife twice and you are ‘hurt’? I’d be devastated and livid all at the same time.

I voted YABU because you just need to leave him. Cheating is never ok. You deserve better.

He's cheated on you twice. He uses sex to manage his emotions. He has to have ongoing and close contact with his ex, probably for a long time to come. I couldn’t stay in the marriage

Sorry. Hadn't seen your update before I posted. Good choice op.

What a prince amongst men. Throw this one back. You are well rid.

You deserve better than this.

I think I'd be telling him to stay away from you, not her tbh.

I had a one word reaction. Cretin. Child ill. Have sex. Oh, come on!

I agree you wouldnt want your DH around a woman hed cheated on you with. Twice.

That said, he cant give you what you want because they have an exceptionally sick son. And his son needs his mum, and his dad needs to support that.

You cant trust him. He had sex with her 6 months ago, hid it and repeated it.

Sorry OP your marriage is over

Luckily as your first anniversary is at the end of this month, you should have enough time to see a solicitor and get divorce papers served to him on your first anniversary.
This time next year you will be free of his revolting cheating self and be able to move on with your life.

You divorce him and leave them to it. The child needs his father despite the fact he is clearly an asshole

I agree. Of course he can’t avoid the ex wife and his sick son, but surely you can’t ignore that he has cheated on you twice? Sadly his son is likely to be ill for some time and his ex wife will need support. It’s a horrible situation for you all.

Echoing everyone else. Absolutely tragic situation for the parents and even more so for the child, but that is absolutely no excuse for sleeping with his ex. There are other ways of being supportive in this situation, sex isn't one of them.
There is no coming back from this because the trust has been broken. You will be doing all of you a favour by letting him go to be with his ex and child. Heartbreaking for you in the now, but better for you in the long-term. I would consider you selfish if your jealousy was the only issue. I view of his behaviour it redefines it as self preservation in my book.

Yabu to "make him stay away from him"

Yanbu to stay.awau from him..

Id be exiting the marriage

You need to leave him ASAP before he leaves you first for the ex.

Your mother is wrong. Is she one of these 'never divorce, what would the neighbours say' types? Or does she consider your dick-of-a-husband to be pitiable, and thinks divorcing him is on a par with kicking puppies?

Not that whatever her reason is matters, because she's just plain wrong; and the correct thing to do is divorce his cheating arse.

agreed.

Omg op he’s a twat and a cunt sorry but you don’t have sex with your ex because your child is ill that’s a bullshit excuse. Op please just tell him to toddle back to exwifey and your divorce will be sorted asap. Ignore the ones telling you to stay no one in the right mind would stay after this happened twice so not really a mistake also why sex why not just a hug or a cry or vent. I don’t think if my dc was ill in hospital I would be jumping into bed with his dad tbh. If ur mum says stay she really doesn’t understand your self worth because it will definitely happen again and again no doubt about it no respect from either off them And using there sick kid is a bad excuse. Omg wow this really is one of the worst op on here.

Leave

Absolutely this

Your mother is a doormat and hard of thinking. She should have taught you that you were with more than this sham of a marriage.
