I don’t have many friends who my boyfriend minds me talking to. How can I use my feminine ways to feel empowered?

You don't need feminine ways to dump that loser. Just slip out the back, Jack. Make a new plan, Stan. You don't need to be coy, Roy. Just set yourself free.

stand on your own two feet and tell him you need friends and your going to have friends. he is not in charge of you.

Dump him. This sounds like the start of an abusive relationship. If you let him control who you can and can't socialise with, he'll only start putting more restrictions on you and you will eventually be trapped with no way out. Dump him. He isn't mentally healthy if he does this. Don't go back; that'll just make him even worse. Dump him. I cannot stress enoigh that you need to leave this unhealthy relationship. Dump him. Yes, I realise I wrote that sentence more than once. You need to dump him. Get out before it is too late.
