What if you did not make it an "all or nothing" thing (break up totally or keep giving in to unchecked feelings)?

Would it be possible to agree to take some time apart, check in with each other after a given period of time, with a few ground rules, and get a sense of where things stand?

Seems like you need some time for therapy to develop without the confusing feelings, and with an agreed upon reunion, you would not need to despair about losing him. Yes, it is hard to be apart, but it sounds unlikely that a carefully agreed upon break would eliminate all the feelings you have expressed for each other...

Just my 2 cents...
