Brain on repeat

I can feel my brain repeating itself daily. Thinking about being with a person who I can't be with. A person who I'm falling for but can't bring myself to be any less selfish about compromising for him.
I don't want to leave my safety net. I'm a home bird- but I feel more like a flightless bird who can't quite find the courage to try. The thought of living anywhere other than here is terrifying to me. The thought of him leaving anything or anyone that he loves makes my insides hurt but I still can't bring myself to even think about leaving my entire life behind for someone. I am not selfless. I wish I was.
In such a short space of time I feel myself wondering what it would be like to have this person, be my person; for the rest of my life. A ride I don't want to be on but I don't want to stop. That is just crazy, I haven't even met him.
