MIL rant

Pretty beyond pissed right now with my MIL. She lives 3 hours away in the mountains and sometimes can be pretty difficult to see her or get up there. We alway make an effort and see her at least once a month. Sometimes twice and I invite her to my ultrasounds to make her feel included as this is my first and her first grandchild. I had to work last night so my fiancé went up to see his mom and come to find out she came to town and planned a bunch of stuff with the family for mothers day and didn't tell us she would be here. We don't get along with his sister because she's an immature pot head that has screwed us over 1 to many times and threaten to beat me up while pregnant. So he tries not to see her an I chose not to at all. But the fact that we always go out of our way and see her and make time to go see her and then she comes to town and doesn't f***in tel us on mothers day really just grinds my gears.
