<human>: Can you condense the text into three sentences or less?

First a little background. I **[28/M]** have notoriously been a relationship kind of guy. I'll have a girlfriend for a couple years, things will end, while single I'll meet the next person and eventually I'll be in a new relationship.

Fast forward to today. I got out of a two and a half year relationship in April-ish. I guess I paniced about not knowing how to date at this age. Now I have all of these numbers, I try to hang out with all of these people, and it is really hard to keep up. Or more importantly, it's difficult to advance any relationships because I don't know who wants what. I should note that I keep all of my dates on the down low and don't even tell my friends I'm going on them. I don't feel like explaining to them how "no, this date is with girl B not girl A."

Do I need to just pick one and try to make it work? I want to be in a relationship, I like being in a relationships. But the way I'm doing things now, it's not allowing me to put in the time to make it progress. 

My other big fear is saying to some of them "hey, I'm going to stop talking to you now because I want to try getting serious with this other girl." Obviously I would phrase it better. But it would hurt their feelings and probably eliminate any chance of something down the road. 

For what it's worth, I'm not having sex with these girls. Although it's come pretty close with some. Some of these girls nothing has happened yet and we are simply talking.
<bot>: Always been a one girl guy. Trying a different approach and it is kind of scary. Not sure how to get back to my one girl ways.
