I've been with DH for 20 years and FIL has made it clear for those years that he doesn't like me.
We don't see him that often (MIL died before I bet DH) but he's just horrible to me; ignores me, makes barbed rude comments about me and of course DH defends his dad saying he doesn't mean it or I'm being too sensitive. I also refuse to join in with the world revolving around SIL, the golden child who is equally vile.
Anyway, he popped round today. DH opened the door and let him in and as he came in I said 'hello' to him and asked how he was. He blanked me. Then when he had sat down I got the usual veiled digs about me and general rudeness. He never asks me anything about me or how I am etc. but today he kept asking how all of DH's friends wives were and then saying things like 'now she is a NICE woman'
When he'd gone I thought about things for a while then said to DH his father is so horrible to me and clearly doesn't like me and that next time his dad comes round I will be ignoring FIL, getting my bag and going out. And won't be engaging with him ever again:
DH isn't very happy and said basically that how I feel doesn't matter.
