Just because they come back to be friends again doesn't mean that even they think it will be at the same level that it was previously & sometimes it's just to be acquaintances again rather than the close friendship that it was before.....there is nothing wrong with that....reconnecting with people from our past is not a bad thing.....it's bad if we expect it to be the same way between each other....it's the expectations that create problems.

It sounds like she just got into a place where she felt the need to reach out to others rather than continue to stay isolated & we usually do that with people we have known in the past because we did care & it's nice to see how they are doing......doesn't mean it will ever be the same close friendship that it was before....& there is no reason to expect it to ever be that again or even that it's what they want in reconnecting.
