This is my reason for not having or making any new friends... That was a hard reality to face. I think that this way of thinking should be considered by a person. I always thought having friends was necessary... It's not and if that's the only reason someone is bent on making and keeping friends, then it's for the wrong reasons. I find people to be too difficult to deal with. Keeping in touch and going out occasionally is best for me...
If you have trouble maintaining friendships...figure out what suits you and what you are most comfortable with. If you're looking to meet new people, I think small talk gets the ball rolling. Idk what to do after that.
