How would you feel?

This did happen to me years ago in a relationship. He tried to keep me from my friends I had prior to the relationship, along away from my family. I was to only speak to his family or friends he allowed me to. He also turned mentally and verbally abusive. It did not last long because I swore to myself to never stay in any relationship, no matter if it was just a friendship, if the person was abusive in any way.

Never again. I ended up isolated and miserable.

It happened in a relationship. He didn't like me seeing family, I had no real friends because I was scared of upsetting things. It's no way to live. If anyone is reading this and someone in your life is saying this to you without good reason, then run, run away fast.

I think if they trust you then there is no reason why they would keep you from your friends or anyone in your life.
Hopefully they would work through their own insecurities. I used to have more insecurities of being abandoned after I was abandoned and disliked people my boyfriend at the time was around, but in the end I found that it was my own personal issue and I would never try to force him to do anything he didnt want to do because I loved and cared for him. If I trust him then there should be no issue.

I've also been in abusive relationships where the guy wouldnt allow me to have any male friends. Felt miserable half the time, probs because of abuse and then being isolated.

I'm the person who tells my boyfriend not to talk to someone. It's his girl friend that he "had" feelings for. She actually had feelings for him too. Did he listen to me though? No. They still talk to this day and were about to hang out for his birthday. 😒

I have, an ex kept me away from friends.
I was young then and stayed away.
Now I wish I wouldn’t have. I think friendships are very important to maintain.

However, friendships do not include ex partners or anyone that a person has shared an intimate relationship with.

I find jealousy to be such a turn off. I would not give into that. Boyfriend's in the past have tried...or I should say ex-boyfriends

It suggests that they don't trust you. Not good

Yes. My ex partner. Turns out they were correct. Those people weren't really my friends

He said he didn't like it when I spoke to certain people. I've since apologised to them.

After making that request, he'd soon be an ex 😌

those insecurities are a bad sign...

Depends on the motivation
