Hi, it's a relief to hear of others in the same boat with 'the mum issue' as one poster put it.
I've lived overseas for a few years, currently in Europe. My Mum finds it very very difficult, and I feel incredibly guilty. DH and I have dd, who is the only granddaughter on both sides.
By a mile, the guilt and upset I feel about my beloved Mum, is the hardest part of living abroad.
She in turn makes me feel very guilty, although she uses all her holiday time and money to come and see us, and I go back to the UK frequently. She doesn't mean to at all, and she is a rock, but I just feel like a huge disappointment to her. She is so family orientated, and adores little children, and never dreamt she'd end up only seeing her daughter and granddaughter once every few months, or on a laptop screen.
Skype is good, but it's also bad, in that I don't have the same quality of conversation on it that I'd have on the phone. An hour skyping is taken up watching dd play or make animal noises (when it's a clear picture), rather than actually talking about our lives, feelings, mundanities. I'm currently trying to spread my communications between email, phone calls and skype video calls, and not just 100% skype.
Sympathies OP, and any advice from other expats gladly taken.
