I have a close woman friend who met a man on a dating site during Covid lockdown. (At that time they were both 70.) They chatted a lot online because they couldn't meet at first! Eventually they met "in person" - and they've been in a happy relationship ever since. Each has their own home: there are no plans to marry or to live together,. They meet up often, to stay at each others homes, and they have holidays together. I've been with them together: it's great how they get on so well. Both are now 75 - and so happy!
