I have a similar problem - I only live about 40 minutes from all of my siblings and their children but do they come to my house? Nope, despite being invited ! The last time my sister came here was after I was ill, 7 years ago!
They all live in a different county to mine, my younger brother and sister and their OH's get together for a takeaway at least once a month - and then post it on FB , saying what a good time they have had. Are my DS or myself invited? Nope!
When we do all get together, about 3 times a year, they talk about football (have no interest) dogs (Ihave a cat), or schools ( 1 niece a teacher, 1 brother a retired teacher, sister teaching assistant and other niece has 2 school age children) and whenever I start a different subject, I either get talked over or ignored.
Quite honestly I wish I could win the lottery and just buy a house the other end of the country!
Since I was made redundant and unable to get a job (believe me I have tried). I cannot afford to go out - benefit just covers rent and council tax so no social life there either. Without my friends on FB, one lives 3 hours away, others in Turkey, Holland and Australia, I could go for days without speaking to anyone during daylight hours!
Maybe Anneishere you need to find people with similar interests - whether on FB, here or enquiring locally at a library or any local newsletters and not worry so much about your family? So then maybe your life won't be wrapped around the rest of your family. Might be worth a try!
