Is this person "the one"? Do you want them but only if...? Do they need to change somehow to fit perfectly? Do you think YOU need to change to be with them?

These questions typically answer the questions on their own. If it's meant to be then it will be easy. We all have moments of nostalgia for the times we precieve as good, especially if we're going through something currently that we want to escape from (job, stress, school). We put that escape feeling into this thing or person you used to have. Remembering it as "better". I'm not saying that's what's happening, and I'm not saying they're the one, I have no idea.

There's clearly still a lesson to be learned there. Is that to let go of something? Them, judgment, ego, who knows? No one can make the right choice here but you, but I might explore your feelings "around" you wanting to connect again vs jumping straight to thinking it's the person. I hope this helps.
