Thanks for the response.
We've started writing out some rules, though it's mostly just notes and proposals so far. Maybe "rules" isn't the best word?
My attitude will change wildly from one hour to the next, which is frustrating for me and probably for her. Earlier tonight I was happy and secure and told her I wanted her to see this guy again (she has not been seeing anyone else for a few weeks). But a few hours later after she finished talking about all her prospects, I felt jealous and insecure again. It's totally irrational, and I know this while I'm feeling it, but I can't keep it in check.
I may have a date myself next week, though.
Not someone I was considering as a prospect. We'll see.
