I didn't and now I feel guilty.
I just feel that she is never considerate to me or even talks to me anymore so why should I her? I only texted her last week to let her know i wouldn't be around as it was a public holiday (Separate occassion to this one) and i feel that if i did so again, i would be hassling her as I know she must hate contact with me. Yet on the other hand, the kids do care and like you say would be disappointed. I feel like I have let them down.
