<human>: This girl and I had been good friends since high school without either of us having feelings for one another. In March, I think she developed feelings for me and we escalated our relationship to FWB. Turns out I'm not good at keeping emotions out of the physical intimacy we had and I developed feelings for her too around late April.

Well now I think she's started to move on from me and I still haven't told her about my feelings for her, even though she probably already knows. I've been thinking of her a lot and I'm feeling pretty sad since I think I screwed up by not talking to her sooner. I've been thinking and I came up with an idea and I'm wondering if you guys think it's a good way to go about things.

My idea is to ask her to meet up, and for me to confess basically everything I've told you guys so far. If she doesn't feel the same way about me, then I want to temporarily break off contact for a few months to allow me to get over her. I don't want to permanently break things off though since we were good friends for a long time without anything going on between us. Is this a decent idea or am I hopeless? Any other suggestions? Thanks.

Can you succinctly summarize the text in 1-3 sentences?
