After being twice widowed, I tried "Plenty of Fish" - and met the man who is now my husband. I agree though, that you DO need to be careful. DON'T, as others have suggested give out personal information such as your telephone number or address. There are definitely people out there who will have lied about their age and/or circumstances, as well as those who are looking to benefit from vulnerable people. I asked for "friends for now", and stated that I wanted to talk at least for a while before any meeting (this was prior to Covid - in 2011). There were a few "oddballs" who responded, but also people who seemed nice. After emailing for a while (through the POF site) I used Skype to contact people, and if they use a computer or laptop, rather than a phone, you get to see them and usually some idea of their home in the background. This would be less obvious with smartphones. We married in 2014 and been happy ever since. Use your own common sense, but give it a try. You can always stop using the site if you are not happy with the contacts you find. Good Luck.
