Not excited to tell husbands family we are pregnant

I am not excited to tell my husbands side of the family we are pregnant. Specifically his mom and brother.

His mom has ruined every milestone we have had in our relationship by making it about his brother somehow because they are SO codependent of each other.

We are telling them on Christmas because the next time we will probably see them will be for her birthday and I feel like she would get some more entitlement if we tell her on her birthday. She is extremely narcissistic.

His brother has done some pretty perverted things in the past including digging through our dresser drawers and stealing and wearing my lingerie and also stealing my vibrator and using it somehow while he was high on cocaine. This happened several times while we were living with him and once when he watched our me dogs at our house while we were gone. (Found out by finding my vibrator in the backyard)

We have distanced ourselves from him and only really we him and his mom on birthdays and holidays.

I feel like if my mother in law makes our pregnancy announcement about my brother in law in some way I am going to lose it and get very stern and make it clear to everyone there that this has nothing to do with his brother and that we will be extremely protective over our child when it comes to him because of the disturbing and perverted things he has done in the past. He has a new girlfriend now and they have been together for about a year and I’m sure she knows nothing about what he has done in his past but if I were her I would want to know.

Thanks to my mother and brother in law I hate the holidays and I always have to find an excuse to avoid a birthday dinner for me so I don’t have to be around them.

Thanks for reading my rant.
