My best friend is really possesive of me?

When I came out, my best friend was the world's most supportive person.
She stood by me, helped me and took me in when my parents disowned me. I still live with her today. We have known each other for years and years, and I love her to pieces as a friend.

It has been a year since my parents threw me out.
I am finally comfortably open with admitting that I am gay, and she has forced me to gay bars a few times to try and 'get me a man' as she puts it. Even though I am hopelessly shy.

Everything was fine until a few months back.
I met a guy online and we flirted for a bit, and I showed her the conversation. She got really angry at me, saying they are probably a pervert who is three times my ages and I should stop talking to them. At first I thought she was just being protective until stuff like this started happening again and again.

When we go out together, she demands to hold my hand just because it is comfortable and she likes it, but she told my other friend it is to make it look like she is my girlfriend.

She really hates it when I talk about boys.

She now chooses what I wear, how I do my hair, she chose the colour of my glasses. She always needs to know who I am texting, talking to online, she has gotten really possessive of me. But we are not boyfriend and girlfriend and have never had that kind of relationship. It is getting harder and harder since I live with her too.

Is this normal behaviour?
Especially since we are just friends, and always have been.
