How often do you hang out with your MIL?

My husband and I have been married for a year and a half and dated for 2. To this day, my MIL has never once asked to hang out with me one on one. We have a pretty good relationship, but I feel sad knowing she‘s never really tried to get to know me. She also complains to my husband that she doesn’t feel like she can “call me up and talk” like she can with her best friends. But she’s never tried to even really talk to me. If we do something fun, she always includes the guys in the family too. She’s a mom of 2 boys and she’s been the only female in the family for 30 years. I’m the first female to join the family after her. I just really wish she would TRY to get to know me and ask to do something together. Just the girls. Just once.

I’m sad venting on here, but, also, is it normal for MIL‘s to want to go do something together with their DIL every once in a while? And if so, how often?

EDIT: We live in the south. Families are very close around here. My in-laws are very kind people and I love them to death. Their family does everything together and I just have always hoped she’d want to do something with me too. We have a lot of things in common (and similar hobbies) and I think we would be fast friends. I just don’t have any married friends and didn’t know if the MIL keeping her distance was normal.
