Posted on another forum but didn't get many replies.
My brother who is in his fifties was cheated on by his wife of 14 years last year. He wanted to try therapy but in July they officially split as she decided she didn't want to make a go of things. He was distraught, crying all the time and nearly lost his job. A couple of weeks on, he met a woman, it was a chance meeting. He is now saying she is the best thing that has ever happened to him, that she has healed the family and that she will be a great stepmum to the kids. This has all happened within 6 months from the kid being told to then being introduced to both his new partner and their mum's affair partner.
Am I right to be concerned? I haven't said anything except to exercise caution which clearly hasn't happened. He is besotted with her and both say they are deeply in love and how lucky they are to have met one another.
