Culag it seems to be that you have had to cope with enormous changes in your life - losing your Dh and moving to a new area. I admire the way you have made a new life for yourself and made friends. I have lived alone for many years but can appreciate how difficult it must be to lose a constant companion. I think it is inevitable that when you live alone, there will be times when you feel lonely, just as when in a partnership there are times when you could cheerfully throttle your other half.
I agree that finding things to do in the evenings and weekends is more of a challenge than filling the days. I sing in a choir one evening, and go to a bookgroup which meets in a pub. I find I do quite a bit of entertaining, if you can call it anything so grand, by which I mean inviting friends over for a simple meal or game of scrabble or even to watch TV together. I have an 'arthouse cinema friend' who likes the same kind of films that I do so sometimes we will do this at the weekend.
I do agree with ga that planning things out is important in keeping the spirits up. Last night I had a lovely evening watching 6 back to back episodes of series one of House of Cards, in my pjs with home popped popcorn. Getting a pet is also a good idea.
I have a very good friend who I know would be very keen to share my house, but she is not in the best of health and I worry that I would end up being her carer. Also, my family live a distance away, as do hers, so it would be difficult to put people up.
I think it's best to just take one day at a time and let the future take care of itself. I do think you are doing very well and it does take time to forge out a satisfactory social life. Well done you
