Am I shutting everyone out?

My girlfriend has been there for three years of my life. I had a lot of goals that I wanted to work on that I was unable to do because she wanted so much of my attention and would manipulate it out of me. Now, I feel like I don't want to talk to anyone and I'm shutting everyone out of my life. It's only been a few days, and I've been reluctant to talk to a single person because I've been so determined to get my goals done. I'm afraid this pattern will continue. Has this happened to anyone else?
