Dating is impossible

So I've tried dating and it's ultimately the hardes Thing I've done. After many years in a situation I've come to the end. It's been so pointless but consistent, if that makes sense. I've been extremely unhappy with him and I have voiced this frustration but he completely ignores me. I have tried to make it into something more but you can't force intimacy it's just not possible. Plus we have nothing in common and it's been a long 7 years of back and forth. It's like you just come back to what your use to but I'm over that. I have dyed in between time just like he has I have seen messages and women and found things out that I just decided to take it for what it was with him. But now I'm ready to find someone and it's hard !!! Dating sites are not for me. And my profession doesn't make it any easier I work overnights at the hospital and I'm in school I have no time and I try hard to mingle but it's impossible. I go to the gym and nothing! I mean I chalk it up to not being attractive so no one approaches me but I mean come ON there has to be someone who wants to talk to me and be my person! Someone I can hangout with , go on dates with, just enjoy simple conversations be my best friend! I know that was a lot but I'm writing in and emotional state so I'm just throwing it out there any advice ?
