BWT, please give me some advice on how to make friends.

Hi BWT! I figured you were the right group to come to. HOW on earth do you make friends??? I'm a 30 year old living in a big city and all my friends moved away. I work from home so socializing is tough- but I tried putting myself out there on apps. I met some nice girls and made plans to meet up with them yesterday and they all bailed. Why does everyone seem so flakey?? Anyways I'm having a hard time forming any connections and I'm getting in my head that I'm just not a likable person. Any advice on how you make friends as an adult would be greatly appreciated!
