STBXH left me and our 13 year old son for a co worker he met on a course and moved in with her 6 weeks later. She is 16 years younger than him and has left her two small children with her ex to be with him. Our son is refusing to see him as he thinks what he has done is wrong. My question is what kind of person is she that she can live without her children? And why do I question how she can do this and do not question how he can live without seeing his? I want to believe they will not last and how can he be with a woman who can leave her children?
