I'm not very sure how such an idea could work amb123 and you have to be very, very careful about who you meet and where.
I do get how lonely being alone can be! It's also quite scary when you're not feeling well/the hot water system fails/there are field mice in the loft or someone tries to hack into your computer, as happened to me last week. In fact ALL of those things happened to me last week!
I have had to be very pro-active in making new friends since my divorce and semi-retirement came at the same time. At first I was devastated, but after a while I would sit with my diary on Sunday and make sure I had somewhere to go/do every day of the week, even if it was just to go to the shops, or get my hair/nails done so that I had conversation with someone each day. I had a policy at first of never turning down an invitation even if I made an excuse after an hour or so and left.
Sometimes I have been in places/events and thought, 'What on earth am I doing here?' I have been to lots of meetings with total strangers, which can be scary, but I always keep it very safe. One of these groups I found through Woman and Home supper clubs. I have made some good friends there and it's free to join.
I found Together Friends through a post on GN. It is just for ladies and I have met one or two very nice ladies to meet for coffee or a meal. There are theatre visits and walking groups. There is an annual fee of around £20.
I have been to meetings of some associations and decided 'not for me'.
I recently attended a meeting of a society who do fundraising for women and girls in the local community and internationally and am keen to get involved with that and also hope to make friends. They do wonderful work. There is an annual fee of more than £100.
I have joined a painting group which meets once a week. No tuition, but we help one another and there are some talented people there. I found a flyer in my hairdresser's for that and I now have a friend to meet for coffee and go to other things together.
I've been lucky in that I still do some work, although it involves a lot of travel and staying away from home so not worth starting courses or paying course fees.
Good luck with meeting people in your area and of course there's GN where we can support each other too.
So don't be alone sitting looking at four walls. It really is important to have contact with people especially in the winter months.
