Asking her to go out out twice a month (it’s every other weekend) is a lot. If she has other friends, husband, other family and demanding job, every other weekend is too often. Yes it would be better if she spoke up about it but maybe she thinks it’s self explanatory.

You do seem to struggle with friendships a lot. It’s not easy. And I am not sure what’s the true problem is here.

Giving her space is a good idea
