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

I’ve tried to talk to family about this but everyone says I’m just being selfish and thinking about myself before others.

Myself 29 female and my husband 35 male have being married for just under a year. Our anniversary is the end of July. My DH was married previously and that marriage broke down 5 years ago. He and his ex had 1 child a son aged 8 and me and my husband have no children currently.

My DSS was diagnosed with leukaemia 6 months ago and we’ve done everything to support. His ex doesn’t drive so my husband has taken on driving her around, doing her shopping and taking her to work. I don’t mind this as I understand she needs to be at the hospital quickly and is not doing well to be getting the bus everywhere. I selfishly though was getting very jealous and had a huge argument with my husband last week. During the argument he admitted they slept together shortly after the diagnosis and then again about a month ago but that’s it. He said he regrets it but I don’t have children so cannot understand his pain like she can.

I have told him I don’t want him around her anymore and don’t want him doing jobs for her but he and both our families are saying I’m being selfish.

I understand that his son is very poorly but I feel hurt and betrayed by my husband.

AIBU to request he stays away from her?

He needs to be there for his son and support his mother as primary carer and co parent. This doesn’t involve having sex with her.

Why are you still with him? You are young enough to start again with someone who doesn’t use their sick son to excuse their own shitty behaviour.

Leave. Now.
Your marriage is over and staying will only prolong the torture.

He slept with her twice after you married and your response is you don’t want him seeing her again? Seriously, get some self respect.

horrible situation for everyone. But that is not an excuse to cheat on you. You are NOT being selfish. He cheated. And will do again.

Just leave. There's no way he can't have contact with her while their child is so poorly, and you can't trust him to be faithful. You only have control over your own actions.

This.

The answer here is to split up now.

On the off chance this is real:

You have two separate issues:

  1. Your husband cheated on you.
  2. You have an unrealistic idea about how much care and time a very sick child needs.

Ending the marriage is the only sensible option.

Do the people who say you are being selfish know that they slept together ?

Bridgertonisbest · 25/07/2026 15:55

Forget it, your marriage is over. He's cheated on you, twice with his ex wife.
