You're braver than me!
About a year after my divorce was final I'd just moved into my house (after living at Mom's for 18 months and saving every nickel I could) when the ex calls up and wants to come over and talk. Uh, okay, but I'm thinking "We're done. What for?" Turns out she wanted to ask my for my approval to marry her then-boyfriend who she's been living with for the last year. Huh
The question just floored me and I didn't know what to say. I just said "We're divorced, do whatever you want".
At the time I had every intention of remaining hard-core bachelor and remarrying, especially to the ex, simply didn't occur to me.
Later on it dawned on me that since I then owned a house by myself maybe she was figuring her entire paycheck would be available for fun stuff. Naw, that's too cynical.
