Hello everyone, as you might have heard I am just out of a 4 years relationship. I am still very young but when I met my boyfriend I was very, very young. I was only 17, I realized that I don't even remember myself being a single person, my life always included my other half in it and it was always the same 1 man. I noticed that I act weird around other men, it is like they don't exist for me, it is like something switches in my had and even my eyes look away. I wonder if anyone else went through this or maybe it is because I only had 1 serious relationship in my life? I always felt bad when someone was flirting with me and I never flirted back because my bf wouldn't like it. I am scared that he changed something inside me that might ruin my future chance for happiness, or maybe I just don't know how to be single? what is wrong with me?
