<human>: My fiancé (now ex-fiancé) and I recently mutually ended our relationship. We had been together for quite a few years. We separated on amicable terms, still very much in love with each other. 

This had been building for a while, and we've had a rough couple months beforehand. During all of this, a very good female friend of mine has been particularly kind and thoughtful in helping out by being a source of support. We have hung out a good bit recently, and it's always a lot of fun. We have had a very solid friendship for a couple years now.

I'm concerned because it feels like I am beginning to develop romantic feelings for my friend. The fact that I have these feelings is something I can't deny– I'm thinking about her too frequently and anticipate our get-togethers too much for it to be anything else than fledgling romantic feelings. I have guilt over these feelings developing so quickly after my relationship ended, and I am also worried that perhaps these feelings are really just a response to missing intimacy and affection and hoping to find it elsewhere. 

Regardless of the reason, though, these feelings are there. My main conflict is whether or not to tell my friend about these feelings. I don't mean to propose a relationship, but just let them know that I have these feelings going on, and that I need to share them and discuss what that means for our friendship.

Is this a good idea? Is it too much of a burden to put on my friend before I have everything totally settled in my head?

Can you condense the text into three sentences or less?
