Should I make it exclusive?

I have been dating these two guys on and off for the past month. It’s been going good with these two, but i have not really felt anything to special. Recently, I went out with an old friend from college who him and I started talking back in college but my ex and I got together and well i had to tell him we couldnt talk anymore.

Him and I have been on a few dates and its going really well. I would love to make it exclusive with just him (to date just him), but i need some adive on if anyone thinks its to soon to make it exclusive or not? B/c I don’t want to scare him away. He talks like he just wants it to be just him and I. He tells me not to drink to much when i go out and to think of him. He calls me all the time and asks if i’ve been a good girl. I think he thinks im seeing him and only him, i have not told him yet that i’ve been dating other guys, and i dont want to string him on. I also dont want to tell him and get him mad and me to loose what could be great.

What do you think?
