sweetowen: Well for me, I've always needed to take a break in between relationships. I don't think it's very healthy for me & definitely not fair to the other person. Whether you want to admit it or not, that next person, if you move too quickly, will end up being a "rebounder". I've been one enough times to know how much it really can hurt. I wouldn't want to do that to someone else.
I have a rule for myself now, that unless I specifically decide to, I will not be the transition person. And if I choose to, I go into it knowing that it's temporary.
