How do you find a husband? 😂

I’m 20, a junior in college, and I’ve been single most of my life. I don’t think I’m unattractive, definitely just pretty average. I get tons of matches on tinder, but after talking for a day or so it becomes apparent that any guy I ever talk to is only interested in sex. So, dating apps aren’t really my favorite thing. I recently met a really amazing guy at a friend’s party (long story short, we talked for 3-4 hours then fell asleep holding hands), but then later found out he had a girlfriend?? We still text everyday though, but just friendly conversation. Someone once gave me the advice to go to the grocery store and just smile at guys I thought were cute?? Yeah, I’m sure you can guess how well that worked. I’m an education major so I don’t have any guys in my classes. I’m involved in several student organizations, I go to events on campus, I literally feel like I’ve tried everything, and now that I’m getting closer to graduating and getting a full time job, I’m worried I’ll never find someone to settle down with. I’m so ready for a long term relationship, and ready to find the person I’m going to marry and have a family with. I’m not really interested in one night hook ups, or 2 month flings. Does anyone have any advice for finding a good man? How did y’all meet your long term bf’s, fiancé’s, or husbands?
