Questions

I met this girl at work. I thought she was beautiful and I asked if I could take her out. We vibed and she eventually said yes. At this point to my knowledge she is single because she told me she want talking to anyone. We went bowling on our second date and I kissed her because I thought it was right. The next time we hang out she tells me that she doesn't want to lead me on and that she has gone back talking to her ex again because ehe blocked her for some reason. She said that it was a mistake kissing and hanging out and that she would like to be friends. I was hurt and confused. So about a week has gone by since we became friends. She told me the reason she felt that way was because I am not her type. We are on our second week of being friends and I can't take it anymore. I think I fell for her. She tells me that she talks to these guys and how they are cute and this and that. Am I simping? I see her everyday at work and I just get my mind clouded and i start to contemplate, then i get sad and depressed and then my say is ruined. I smoke weed to try and cope with my emotions but its not working this time. I want to love her but she doesn't love or even like me. I did this once in HS, I was depressed most of the time at school. Im just confused on what to do… i know what must be done but I can't. I need advice… please 😢
