Q I broke up with my ex about three years ago. He wouldn't stop cheating, and I just got tired of it. I've moved on and plan to marry within the year. Over the past few months, my ex has started texting me provocative things, telling me how much he misses me and trying to set up coffee dates with the excuse of discussing the kids. I try to play it down, but it's getting worse. I'm afraid if I shut him down, it will interfere with our co-parenting. We have three children. Should I tell my fiance? What's good ex-etiquette?
