Partner turned off (My) wifi and upset my Son - AIBU

Dump him. Take a moment to be glad that he showed his true colours before you enmeshed him any further in your child’s life. Don’t introduce your next boyfriend to your children so quickly and don’t be so quick to describe them as a ‘partner’ when they are clearly nothing of the sort.

There are so many things that your "partner" did that are red flags to me.

1. Decided that somehow or other that because he is male, the house that he is living in is his and he gets to set the groundrules.
2. Following on from 1 above, that children that he has not adopted and has no legal position over, were to follow HIS rules
3. Following on from 2 above, that he divulged what went on to his mother, and she is now being one of his flying monkeys trying to get you back on his side (which is all sorts of wrong).
4. Not apologising to your son
5. Not apologising to you

They are the top 5 things that just off the top of my head I can see that he's done wrong here.

Ditch him. He is not a positive influence in your lives. For all of his failings, and I don't know the background and circumstances over why you divorced your Ex, but your Ex is coming across better here than this specimen is.
While your partner is out of your house, I'd go through the house, room by room and bag/box up everything that was his and leave it out on the front porch for his mother to collect (seeing as how he has involved her, she might actually be of some use to you). If she doesn't collect, they'll be going out on the next bin collection day and then throw the stuff out.

Leave him. He sounds awful.

This. Dump him yesterday OP.

9 pages later and I don't think it's too far of a stretch to say op was not being unreasonable. 😁

He would be my ex by now-put your kids first.

can you imagine if you lived together what that would be like? And you would end up losing your home as it sounds like he is an entitled prick and would go after it in any split. And tell his mother to fuck off and keep her nose out as it is literally fuck all to do with her how you look after your own children

I ended up kicking my partner out - He went home in a huff and now I'm being put in the middle by partner's Mum saying that I should teach my children respect

How are you in the middle?

Surely he's now an ex & so he & his mum have now been blocked?

He cut the wifi that you pay for in your own house because your son did something that he didn't like?

So he thinks fuck all of you as well?

What an utter cunt! As literally everyone else has said - don't ever let him back into your home or your life. And his stupid mother can fuck right off as well. Your children deserve far, far more than some useless wanker throwing his weight around in YOUR house.

Under his roof but it isn't his house. Nope ick. Gross, your well rid!

Honestly, block him and his horrible mother, get them out of your childrens’ lives.

Mn has a great word for this breed. Cocklodger I believe. Well done op for getting rid.

You did the right thing, please don’t bring this horrible man back into your children’s lives. No relationship is worth damaging your relationship with your children. Or worse, damaging your children emotionally overall.

My partner cut the wifi when my son didn't come to the table.
How dare he! Bully. And assuming authority that isn't his. Get rid.

He started ranting and raving how under HIS roof my son should have more respect. I reminded partner that we live in 2024, not 1924 and the house I owned was mine that my Mother left to me.
How wrong can a man be? Look at what he's doing - claiming your inheritance as his own.

I ended up kicking my partner out
Sensible woman. Well done. Keep him out.

now I'm being put in the middle by partner's Mum saying that I should teach my children respect.
Not her business. She can fuck the fuck off. Get rid of 'partner' (10 month boyfriend) and with him, his mother.

Letting this man into your children's lives was a mistake. But you sent him away, and if you keep him away, that will be much better.

He should 100% stay an ex boyfriend- the big bully!

Also his mum should teach her son some respect.

End things with the man and show your children that they come first. He was controlling and unreasonable.

Not his house, not his children, not his WiFi. Tell him to fuck off. Also perfectly reasonable to allow your child to stay upstairs if they weren't feeling well. Sitting watching everyone else eat might have just made them feel worse.

He would be gone so fast his arse wouldn't know what kicked it.

You did the right thing.

Don't have him back.

It's also so nice to read about divorced parents coparenting well and haven't good flexibility. I'm glad you didn't allow a new partner to disrupt that.

A very unpopular view but I think this is the OP's fault. At a new relationship with a boyfriend of only 10 months living with and inflicted on her children. So bad for these poor children.

A bit confusing when you say he isn't a live in boyfriend when he is just that. Unless he doesn't live with you in which case more shame on you.

I hope this isn’t true because it’s absolutely ridiculous!

Its been 10 months and he should have absolutely no say on what happens in your home or with your children.

The fact that his mum is involved is absolutely bizarre!

The relationship is over.
There should be no discussion or second chances.

Its actually quite scary how after 10 months he thinks he has some sort of dominance over you, your kids and your home.

I think you’ve dodged a massive bullet here OP and although you’re going to feel a bit sad it’s over, I think you should be thankful that he shown his true colours before he moved in properly.

Thanks for explaining because I really didn't get it but I'm thinking in this situation it wouldn't be teaching respect for others it would be teaching your kids about having respect for yourself.

Dump him, he’s abusive!

Ten months! You might like him. But way too soon to impose him on your children.

Someone needs to be taught some respect alright. But it's NOT your son.

Perhaps suggest to your STBXs mother she cracks on w teaching her child how to behave in other people's home next time she complains.
