ignore em and if they don't like it ef em
Well, it depends. If they live with you, you have to compromise. Otherwise, f them.
That's a tough one. It can cause a lot of strife. Sometimes we can just ignore the in law. Sometimes it needs to be addressed. Meaning in as nice a way as possible, tell them to butt out. I could not come up w/a more polite way of saying it. When we were younger, my husband's dad ALWAYS had his nose in our business. Caused A LOT of unnecessary problems. Thank God he moved away and he is now occupied w/his gf. You sometimes need to be firm, but respectful as these people are your elders. It's not easy. I feel your pain and frustration.
That's an age old question with no answer, ever.
No name calling or aggression, but the only thing that "might" work is IF your husband goes on the same page with you, and he communicates to his parents not to meddle in your affairs.
Nope, everyone should have their own place. Her mom has her own life to tend to. If she is bored, she can get a hobby instead!
