Would you be comfortable setting a boundary with them? I had to do this while separating from my husband, with my mom, my dad, my brother and one long distance friend. What I said was:
"I am doing the best I can to make decisions for myself and my children. I appreciate that you care, but it is not helpful for me when you tell me what to do. If you can't refrain from bombarding me with suggestions I'm going to need to take a break from talking with your for a while. I love you and value our relationship."
It worked, to an extent. My dad doesn't really listen to anyone, so I just end up tuning him out completely.
