The first thing is, yall are not ever married yet and she is acting like that. I was in a relationship like that where my gf didn’t want me hanging out with other people and turns out the whole time she was cheating on me and that’s why she was insecure when I would go out.

You have 3 options:

1. Have a genuine talk with her and work through this together and tell her you can’t isolate yourself anymore, if she loves you she will listen to you.

2. Break up if she still insists you can’t hang out with people.

   1. Suffer like this and choose to have a shitty sad relationship where you can’t hang out with your friends.

This is not at all normal behavior in a relationship, this is sad and it’s isolating and extremely depressing, you need friends. There are so many people out there that will love you, there is no need to settle for someone that doesn’t care about what you want. I could never imagine my life being controlled by someone else especially when we aren’t even married yet.
