@nergdron depends how much spare time you have... :p I've had 2-3 partners at a time and found it too much after a while, but I also have like 0 emotional energy most of the time so that might just be a Me Thing.
@cmdrspacebabe yeah. it's like... i love these people. but i know i'm not being a great partner trying to juggle them all. gotta figure a way to sort it out without hurting anyone, if possible. *sigh*
@nergdron yeah. I have friends who've had partners overdo it and wound up spreading themselves too thin - except they refused to admit it or communicate about it, which is obviously not the right choice. Definitely best to be honest about it and try to figure out how best to ration your energy.
