I've brought up my DC (12 and 14) alone since DD2 was 7 weeks old. Over the years Ex-H has lied to avoid paying maintainance and only in the past year has he chosen to have any contact with my DC, once a month for about an hour. That aside he was violent to me during our relationship although he wouldn't dare try it now, and is generally a "big I am " type of prick.
DD1 has recently hooked up with him on FB. So, I took a peek, like you do. I read of his recent engagement, his holiday, the new 3 piece leather suite and so on.
I know its childish and I have no intention of doing it but I am so tempted to post some remarks. Such as....
"Glad you had a good holiday. Shame you couldn't afford to buy your DDs shoes"
"A weekend off? Pity you didn't have the time to visit your DDs for more than an hour"
"Congratulations on your engagement. Sad that your DDs had to learn of it on Facebook".
As I said, I have absolutely no intention of saying a word, but AIBU to want to?
