Haha well as u know my ex has NOTHING. His shitty personality changed him not money. The new always wears off. I'm sure ur ex kicks himself in the ass for what he did to u and ur family. My friend told me ur ex works with her husband.
Never go back! And if what broke you tries reaching out to you again, ignore them. A valuable lesson for everyone to know. If they broke you to begin with then he didn't love to fight and be better for both of you.
