How to deal with my issue?

As a child I was very anti-social because of a crazy mother. I was this way for about the first 17 years of my life then my personality changed and I became an extrovert but this caused some paradoxical shift and the effect on it made me become a clingy and very affectionate person. I don't however display all of it to the girls I like but it eats away at me and makes me depressed when I can't just hug them and kiss them 24/7. I am currently getting closer to this girl I really like but my illness is starting to take hold of me. We are currently living together and it is amazing but I still want more closeness but we are not even dating and I am to nervous to ask her out because if it spooks her I will might be kicked out of her place. She is a very independent girl and it hurts me, I sometimes resent her when I am not included in her daily activities. Any advice to my issue.
