Finding a relationship

So I am 23 and single, starting grad school in the Fall and I am panicked a little. I am moving into my first apartment alone and I am terrified because I am not dating anyone.  I figured by 23 I would be married and pregnant and have an awesome job or be a SAHM,  I feel like that's how life should be for me.  Instead I'm in school without a boyfriend:/ I don't know what to do I mean I do online dating and I go out to bars and i am just getting pissed. Most guys just want hook ups or to hook up then see where it goes. I'm just not willing to do that, I need to be in a relationship before I have sex so it's meaningful.  Idk what to do I mean my grad program is about 90% women so I doubt I will find a husband there.  I just feel like I'm getting older and I wanted to be a young mom snd I'm not super young anymore.
