Social life

I have met a lot of people and have many groups of friends but I believe I handle the interactions with them badly. I tend to get absorbed with one group and neglect the rest. Which isn't that bad though, because I need time to get to know them better. The issue at hand is that I don't know how to balance everyone out and navigate through the groups. I guess that comes from my all or nothing attitude, like wanting the group I spend my time with to be my all, and always be as I please. 

Guess I'm also jumping to conclusions and start being analytical or judgy with people. Then, when all the pressure builds up, I invent some crazy idea so that I can blame them and run away as it cannot be my fault.
