I sympathise Op, we arent very social but am part of a small group of mums (4 others) who used to see each other lots for coffee and meals, less so now DC are older, but still have meals as mums or couples a few times a year.
One is a neighbour who we supported massively last year when her husband had a bad accident.
I emailed them last week inviting them to 2 fundraising events, one an Indian meal for my DDs guide trip, the other a quiz night being held by an acquaintance (who has said they will come to Indian, would we like to go to their charity quiz).
Being a quiz, we didn't want to go alone, but all 4 so-called-friends have come back saying they are busy both nights. None of them have big social lives, so unlikely, just wish people would admit they didnt want to come rather than lie!! I just really feel like billy-no-mates at the moment.
Hey ho, think we will offer a donation in lieu of attending the quiz, and the Indian night, well we will enjoy it!
Two of the group also have dogs, as we have had for 3yrs. I know they walk regularly on Mondays, when I am also off, have see them, but I have only been invited to join them if I specifically ask them if I can. I find it very sad, dont know if I have done anything to upset them - one I have known since our eldest were born 19yrs ago.
