Sorry for bumping an old thread but I totally understand what everyone is going through in this thread..
I'm currently in a relationship and I feel very attached. My girlfriend is attached too but I'm a lot more. I also feel like its because I don't have many close friends and other options. I too have had close friends move away or become unstable to the point I can't hang around them. So I'm very dependent on my girlfriend. Its a very new feeling, before her I was someone who cheated and didnt take girls too seriously. Now I'm faithful and in deep love and I'm miserable when I'm away from my gf.
