Need advice

Christine
If you broke up with your fiancé of 4 years(he says we're taking a break, that it's not a permanent split), you still stay in contact and talk, and he starts talking with other girls(just as friends), do you have the right to be upset? Should you keep in contact so as to remind him of the good memories you had together? Or should you be distant/hard to get, and will that make him miss you and want you back?
There's so much more to this story but I don't want to rant or rehash it. I'm well aware that I "could" just move on to someone else, but my frame of mind isn't there currently. I still love him and while I might be upset, I love him more.
