Why does it seem like it doesn't work with any guy? I try to keep an open mind ....?

I'm 24 and it's not like I feel I want to get married but I want a more committed relationship other that going out and having fun. I try to keep an open mind and it's not that I'm settling , I just came to realize that life is not black or white. People make mistakes and at what point I was against dating men with kids because I didn't have any. However I questioned myself how about if it was me with kid would I like someone not to date me because I had a kid? However even a guy with a kid doesn't seem to work out... I'm frustrated because even my social life is on pause or has slowed down most of my friends either live with their boyfriends or are married. Fridays arrive and I have no one to go out with... So it's not even a point of me being single it's a point of not having an active social life as I used to. I feel like I'm where I need to be I have a descent job, I'm working on m masters, etc. Please feel free to offer enlightenment ......
