My best friend is my crush

I had my best boyfriend but he loved me and our friendship ended.I didn’t think that he liked me but then he brought me a rose and said me things like I will only give back your phone if you kiss me ect.He said several times he loves me and he was so sweet.So after these I stopped texting him, but we were always friendly.I was afraid to lose him because of the fact that he loved me.To be honest I felt something too but I wasn’t sure and ready for a relationship.It happened about 2 years ago and now we’re getting closer again (like friends).But I feel like now I’m the one who start to feel more.I don’t really know what to do I’m love him. I have a crush on him for sure.
