Am i wrong ?

I’ve always had a decent relationship with my mother in law. lately it’s been really rocky and she’s become such a bully towards me and my son so we stopped visiting her.

Every year on my sons birthday we tell her 2 months early. we tell her how much she’ll need to save and dates and times and continuously remind her. Every year she never saves the money and me and my boyfriend have to pay her kids way in, their snacks if they want plus their gas to get to and from the party. 2 years ago we had to pay the registration on their vehicle. she ALWAYS plays victim because she knows her son will cave and pay.

This year i had enough. she started to pick on me and my son. claiming we only visit to steal from her and is just blatantly rude towards us so we stopped coming around. She hasn’t once called or anything in regards to our son. I told my boyfriend we are not paying her way this year and if she can’t manage to save the $ to come then she can stay home because i was fed up.

so of course she’s been told countless times throughout december and january about the party , waits till a week before the party to try and play victim with her son who denies her and she gets mad.

she convinces a mutual friend who is like a daughter to her to give her the money to pay for her two younger kids. Then calls me. I don’t answer at first because i was well aware why she was calling as the friend has messaged me about it but was busy so i didn’t answer. after an hour i called my mother in law back. she proceeded to call me a bitch and yell at me , on speaker phone infront of her other daughter in law (boyfriends brothers girlfriend who is my friend) about how i always ignore her. (she never calls me) and explains to me how she borrowed the money. how my father in law will drop the younger to off at the party and when i ask who’s going to be watching them (they are 10) she proceeds to tell me that other people are there and it’s not her problem. i keep my mouth shut as i don’t want to deal with it. she then tells me she’s not coming cause she’s playing bingo later on and doesn’t want to miss it. so i quickly get off the phone because i’m beyond irritated.

my boyfriend has a sister who lives at home (she’s 20) with her girlfriend.

the sisters girlfriend calls me to tell me that my mother in law is claiming i’m. stuck up bitch and a c*nt because of the way i acted on the phone and how she doesn’t even want to bother with the party.

Am i wrong to be completely disgusted by this entire situation and not even want them to come ?
