should I do it or not

Date: 5/23/2016

I have this fat crush on this girl but she has a boyfriend. We have liked each other for a while and always talk and just last night. I had a dream about her. I went to her work gave her a kiss and told her to be mine. She said yes and we hung out all day and then left the city. I woke up after driving away from the city. But Is it a sign todo it??
