Relationship advice

My bf and I have been together for a few years. We live together.

He is a recovering drug addict. I didn’t know him when he was in active addiction. I met him and started dating him after he had time in recovery.

He still goes to a couple meetings a few times a week.

I recently found out that when his sponsor let him start dating, he had a thing with a girl that is also in recovery and goes to those meetings.

There are a lot of girls that are in those meetings and I saw on his social media that he’s friends with a lot of them.

This might sound weird, but sometimes I feel jealousy that he can relate to them a lil more and I can’t relate with that. I have never done drugs in life. (Which I am extremely proud of). But I can’t relate to him with that. He can’t talk to me about that kind of stuff.

Some of his friends that go to those meetings have girlfriends/ wives that are also in recovery. After the meetings, sometimes they all go out to eat. And I can’t go because I don’t go to the meetings obviously.

They also go on little vacations together. And my bf went with them before he started dating me.

Idk. I just feel left out of that side of his life.

Any advice ????
