Ways to meet more friends

Hey this is going to seem like the loneliest post ever but for the past three years I’ve been in a relationship with my boyfriend. He’s got so many friends and I’m 23 and feel like I have no one. I only have one real close friend and I wish I just had more people to talk to and go do things with. I was just wondering if there were any ways you have met your best friends or close friends at the age of 23. I own my own business too so it’s not like I have any one that I can talk to from work as well. I just want to meet more people that’s all. Thanks!
