In January I have a birthday trip to my sister in law 40th. Which is a 4 hour train journey away. We have a turbulent relationship, she is disrespectful to my mum, she keeps her children away from seeing my mum who has only ever been a loving grandmother.
I feel so torn about going as she has caused so much trouble in our family and let’s her mouth run away with her.
Another reason I don’t want to go is that I have a 10 yr old and 7 yr old and I run my own business in which I would lose takings in the time we will be away. My husbands work is so busy in January that I feel bad leaving him for 2 days, although my mum would help with childcare his mum has also just had a mild stroke, so are under pressure in our family life.. our lives in general are so busy.
If I refuse to go giving the above reasons I feel she will not understand, and be made out to be the bad sister in law
Please help I am being unreasonable
