I am not entirely new, posted couple of times over the years, but could not find my email account. anyhoo......
My mum moved abroad, as the weather makes her feel better there, she has 1 family member her own age nearby, her sister and she had a holiday home there already, it was a reluctant move but only within Europe and she did not want to leave my kids initially, who she was close to and are now in their teens..I said to her, we would visit (once or twice a year), skype, etc and we have done so.
However as soon as she got there, her neighbour (a local) which she vaguely knew beforehand, who has young kids, has become her best friend, which I thought was great, and I still do think it is benefical partly, as she takes her out, and the kids are getting close to her too. It seems to have crossed the line though, this family is all she talks about now, and they are going on trips and she has put off coming to UK to visit during the hols, because this family had a prior plan with her! I cannot quite get over the uneasy feeling, but not sure if I am feeling unreasonable. Not sure if it is jealousy or think she will be sucked in too far, not so much now but as she gets older...I have not said anything to her, although she can probably sense my annoyance when she only talks about this family and nothing else!! My husband and even her sister did say a couple of things/hints about it too.
