Do you think it's rude if I try to avoid my divorced mom
Is there any reason why you would want to avoid her?
She just looked very sad most of the time, and I don't want to deal with that.
It's understandable it may be difficult to deal with people's emotions that times. With that being said, you should really try to be there for your mother in her time I need.
I understand and I did that. That's all.
It's great to hear that you have checked on your mom. It might be hard but continue checking on her at least once in a while, so she knows you still care.
