There is nothing wrong with the whole not having a girlfriend aspect. I am 26 haven't had a girlfriend since I was 17 in high school probably because I am shy
. I don't look at it in a bad way though. I'm an introvert by nature and I don't really enjoy talking to people a lot. I truly enjoy my alone time. The bottom line is if your mom hadn't of brought any of this discussion up you would probably be okay with yourself right? Don't do a complete 180 with your life just to make your mom happy. If you were already happy then shouldn't your mom be happy that you were happy? You should only change if you feel you need to change. It's your life and every body lives differently.
