Input: My boyfriend and I are involved in a bowling group that we found through my best friend Alice and her husband. There are about seven guys on the team, but only three girls: myself, Alice and Beth (whose boyfriend is also part of the group).

Alice and I have been best friends for years, and one of our hobbies outside of bowling is going to breweries. Sometimes we invite a big group (Beth included) and sometimes it's just the two of us. We've been doing this together longer than we've even been in the bowling club.

Beth saw a photo on social media of Alice and I at our most recent brewery adventure and she was really upset she was not invited. Her boyfriend reached out to my boyfriend to say I was an asshole for not inviting Beth despite her really wanting to be more involved with "the girls" (again, Alice, Beth and I are the only girls in the group). 

Am I the asshole? On the one hand, I feel like I am allowed to hang out with my best friend doing our thing without needing to make it a girls group outing. Also, if Beth wanted to hang out more, I would be happy to join in if she organized anything. On the other hand, I understand she feels like she is being left out simply by being the only one not invited on the "friend date". I don't want to hurt her feelings, but does that really mean I need to invite her every time I hang out with my best friend?
