What do I do!?😩

Sooo me and my so of 2 years broke up about a month ago.. I’m still not over him but it is what it is and I honestly just have to learn to live with it .. I also have had this bestfriend for about almost 3 years and I’m starting to feel like I’m into him.. but what if he isn’t interested?? I don’t want to ruin our friendship but he is someone that I wouldn’t mind being with... we stay up late and have the deepest conversations, go out, and have lots of fun.. he’s just so handsome and he’s always there when I need him to be. I have no idea what I should do.. should I pursue him? How?? What if he doesn’t feel the same? Please comment your thoughts, it would be very helpful! 🤭
