Hi pins tony
So maybe it is time for you to seek out some company, that's not selfish, it's a human need.
Maybe though, from your reaction, it's not really the right time for dating as such - messaging people on the site may help you get chatting again and be a beginning of a more social you (please do make it clear to any ladies exactly what you are and are not offering so no-one is even remotely misled)
There are other possibilities, as well. Have you thought of volunteering - maybe in a charity shop or to help out at a lunch club or whatever is local to you - that way you get to work with others, meet a whole bunch of people and make a difference which is satisfying.
Or join an evening class, something you've always fancied doing - or something you never thought you'd try.
There are lots of clubs in my area that have monthly meetings with speakers - and the library has coffee mornings with talks. Is there anything like that near you?
I've found that most of the events I go to have more women attending than men - and because we are all there for a reason, eg an interest in local history, there's something to chat about which makes introductions less awkward.
