Oh so good to hear from you! Aren't you just hating this heat?
I think your ex is afraid to be alone and probably thinking if this aren't good with OW, let's see how things might work out with Olive. My ex married his OW. We get along but aren't friends. New wife...same as you, don't bring her around me!
I guess the question you need to ask yourself is what do you see in him that makes you still consider being with him? Have you been dating? That might have got your ex thinking about you. Sounds as if your ex hasn't done any work because gee, he hasn't had to.
