AITA for taking my son's side in his divorce, even if he is being " Superficial"?

Family loyalty can become complicated when divorce enters the picture, especially when children are involved. In this situation, a mother found herself defending her adult son’s decision to leave his marriage, even as other relatives accused him of being shallow and cruel.

What makes the story more complicated is that the conflict does not stay between the couple. A close family member sided with the son’s wife and openly criticized him, framing the separation as abandonment over appearance. As tensions rose and court proceedings loomed, the mother was left questioning whether standing by her son and offering him and his children a safe place to stay made her complicit in something unfair. The situation sparked a wider debate about support, boundaries, and when staying neutral is no longer possible.

This situation reflects the tension between emotional support and perceived judgment during a family crisis. From the mother’s perspective, her priority is her son’s well-being and the safety and stability of her grandchildren. Supporting him with housing and emotional backing does not automatically mean condemning his former partner, but it does signal where her immediate responsibility lies.

From the niece’s point of view, loyalty to a lifelong friend may be shaping a simplified narrative. Framing the divorce as abandonment over weight overlooks deeper issues described in the marriage, including refusal to seek medical help, limited mobility, and uneven parenting responsibilities. These factors often strain relationships far beyond surface-level attraction.

On a broader social level, the story highlights how quickly divorce discussions can become moralized, especially when health and appearance are involved. Families often struggle to separate compassion for an unwell person from accountability within a partnership. The conflict underscores how difficult it can be to balance empathy with realism when children’s care and long-term stability are at stake.

Here’s the comments of Reddit users:

Many users supported the mother’s decision to stand by her son and grandchildren.

Icy-Significance-337 − NTA. He left her because he was unhappy - for whatever reason - otherwise he would have stayed. That's how it goes. There's nothing wrong as a parent...

It's his choice, and this is your support. Would have been shittier to be on the other side and simply put peer pressure on him to be in a situation...

astringofnumbers4082 − It sounds to me like he didn't leave her because she's overweight, but because she's not being a good partner or parent and refuses to change. I think...

[Reddit User] − NTA. Those don't sound like superficial reasons to me. I assume it's mostly because of her mental health, not her weight.

But also, you're a 46 year old woman, don't engage in a 25 year old's drama. Edit: I didn't realize that she said she raised her niece for years, so...

Obviously it's more nuanced than that. However I think there's still a definite need to set a boundary with her, or at least to try to have a civil talk...

As for your niece you need to tell her to stay out of their marriage issues. You will not turn your son and grandkids away.

If your son has offered her help and she refuses their isn’t much more he can do to help her. No mater how much you love someone you can’t let...

Some commenters added nuance, urging boundaries and a broader understanding of health issues.

Sea_Supermarket_9728 − NTA - support your soon and give them a place to stay, but keep you opinions to yourself.

People don’t get that size because they want to, it is a result of years of negative behaviour stemming from untreated mental health issues.

Your son has reached his limit and wants a better life for his kids. It’s understandable that he wants to get away and protect them.

Your niece has chosen a very black and white view of the breakdown of your sons marriage, most likely influenced by the ex-wife/best friend.

But the truth of the matter is, your son is obviously not leaving her simply because she gained weight.

There is a much bigger issue going on with the ex-wife that she refuses to get help for, and her weight gain is a side effect, who knows maybe she...

Your son can't navigate the marriage on his own, and for the kids he has chosen to do what he believes is best for them. NTA

A few responses were blunt and emotionally charged.

[Reddit User] − NTA. 300+ is not a few extra pounds or a little overweight. That is morbidly obese. That is a serious health issue for which she is refusing...

She isn’t mobile and can’t/won’t take care of her kids? I’m sorry, no one should have to put up with that. It’s like an a__oholic who refuses to get help.

Your son deserves better and so do his kids. I hope for all their sakes she realizes how serious this is. It’s not shallow at all.

[Reddit User] − NTA: it’s more than reasonable to leave a partner who won’t take care of themselves despite being morbidly obese. Is it painful? Yes. Does it hurt everyone...

Yes. Does your son deserve to spend the rest of his days being a caretaker because someone with physical and mental issues refuses help? No.

You’re being a good parent by supporting your child with his reasonable decision to not spend his life taking care of a whale who won’t seek help. NTA
