I am sick to the back teeth of the lot of them.
MIL is controlling and I find her quite creepy in her ways. For example she’ll start silently filming arguments robust discussions between other members of the family as well as the dcs when they are ill.
FIL is stubborn and dogmatic. Financially abusive (wouldn’t let MIL have access to joint bank account until recently when MIL started getting a pension).
SIL is a bully and drama llama. She is very spoilt and throws tantrums at the age of 35 if she doesn’t get her own way. 
I should have known I’d end up hating them from the beginning when DH would drop little hints like, for example, if a new person joined SIL’s workplace and she was female, DH would give a little laugh and say “well she won’t last long! SIL can’t have another woman competing”. 
I hate them so much. I hate having to see them, resent having to spend time with them.
Unsurprisingly it’s driving a wedge between DH and me. I know it’s causing him a lot of distress.
To be fair though, they don’t know how much I hate them. Well, unless DH has mentioned it which I really don’t think he has. I am always super polite and friendly around them. But I feel like I’m dying inside whenever I have to see them which is around twice a month.
Does anyone have any advice on how I can cope with the in-laws without heading for divorce?
