My DM is very close to her sister but rarely bothers with me and my DC.
She spends almost every bit of her free time with her sister but is forever letting me down when we make plans, she never calls or picks up the phone unless she's at a loose end and needs something.. but she talks to her Dsis on the phone two to three times a day and spends most days in her company.
My Dbro is treat very much the same although he doesn't seem too bothered about it, I am.
We'd planned to have supper and a catch up tonight but she called me and cancelled last minute to say she's decided to go to her sisters and have a drink instead.
I'd say the pair are co-dependant but that doesn't take away from the sadness I feel that she'd rather spend all of her time with her, than any at all with her own daughter and grandchildren.
I've now gotten to be quite resentful toward her sister as a result of it.
Am I being ridiculous ?
