It's just a matter of avoiding that breaking point, I think. And it's difficult for me to tell when it's getting to a point of no return or whatever, so I just try to keep more than enough distance. I could see an ESI not having this problem though.
Yeah, that would actually be a lot easier, I think. Peter tends not to be interested in hanging out with new people though.Once you or they are married though, it's different. You can still be friends, but you switch to being a friend of the couple, not the individual.
