We have been together 20 years but he had just broken up with his fiancée before we met. She suddenly ended things and moved away to be with someone else. I know he was heartbroken. A few years ago I discovered he was still messaging her regularly. They all seemed fairly innocent messages but they were about every bit of his life, our child, his boss, everything. There were no plans to meet or anything but they were messaging a few times a week minimum. I was furious and insisted that he stopped and he seemed to. Today I realised they’ve been messaging again. On the face it’s quite innocent chat, but he always mentions a bit about her that he really fancied. We are not in a good place. Lockdown has been very hard, yet logistically it would also be very hard to break up. I don’t know what to do - ignore it and hope it blows over? She isn’t in the country so it’s not like he can actually see her. Or accept that he will always have a weak spot around her. It doesn’t feel fair.
