<human>: Condense the text into a few key points

Hi!

I [24 M] am starting to get very strong romantic feelings for my ex [23 F] since 5 years.

Our previous sexual relationship lasted 3 years and was the first relationship for both of us. We separated as friends ( although it was tough for both of us ) and have remained in contact ever since, seeing each other regularly. Although, I have always been under the impression that we will eventually get back together.

Since then, during the last 5 years we have both been in other relationships but remained good friends. I would consider her my best friend as she is always there for me and vice versa.

Now we are both single and an attraction is building up again. I am in love with her. She has very strong feelings for me but I am not sure it's in a romantic way. I think I see hints that it is mutual, but I could be misled into seeing what I want to see.

I want to and will tell her, but not sure how. I am resisting the urge to just tell her that I love her, and hope for the best. Maybe I should explain that I am starting to get feelings for her again, or just let the relationship evolve gradually by hinting more what I want. I don't know what to do! How would you go about it?
