I feel as if she’s more interested in talking to my oh than with her child.
How much talking is a nursery aged child going to really do though?
On each FaceTime she will spend a couple of seconds saying hi to the child then switches to wanting interaction with my oh (mainly about crap)
The thing is it can seem like a very businesslike transaction, if she just cuts off or if he just cuts her off after speaking to the child. As their child gets older, your OH will not need to facilitate the facetiming, so her chats can't really happen in that way, unless he wants them to.
It sounds like she uses him for a chat when she's alone.
I don’t feel like I need to change my response I feel like he needs to stop engaging in her games as that’s what I feel they are
My point in saying you need to change your response, is that your feelings of resentment are only affecting you. So you can change and not let it bother you, don't change and it continues to bother you and it could escalate or walk away.
You want him to change, but he won't. So where does that leave you?
He either knows how much it bothers you and isn't moved enough to do anything or maybe he doesn't realise how it affects you.
He could also wonder why it's bothering you so much, when he isn't bothered.
It's like any relationship really...if you don't like the way someone behaves....and they have no desire to change...the onus falls to you to accept it (happily or unhappily) or remove yourself from the situation for your own happiness.
I know she annoys you, but you need to get to a place of realising you have no control over her behaviour.
Men often can't be bothered with this kind of conflict with an Ex. I know my ex SIL was super friendly and it made my new SIL a bit uncomfortable...that was her own insecurity.
My brother wasn't going to be nasty or cut her off, because she's the mother of his DC and it would have a negative impact on them.
He often said to me that she does chat a lot, but then she was always a very chatty friendly person. Their divorce (amicable) didn't change her personality.
He has previously said he can't wait till their youngest is 18 and he doesn't have to communicate with her.... this isn't something he shares with his wife...Maybe your OH feels the same deep down.
I have told my brother that just because a child turns 18, doesn't mean you don't ever talk to the other parent about them again.
Weigh it all up and decide if this is that big of an issue for you. If it's really making you unhappy in the relationship, is it in your best interest to stay with him.
Look at the whole of your relationship and think about whether everything else is good except this.
Ultimately, you need to decide whether it's a dealbreaker on the basis that neither of them will change in this respect.
I must say her phoning his mum is incredibly childish. That would piss me off.
I'm honestly trying to help and support you. I understand you don't like the situation, but accepting you can't change that is the first step.
On the other hand if she just irritates you and your thread was a general 'get if off your chest' one, then you could just continue as you are.
