Agree he hasn’t respected his marriage vows to date, but people can and do change. If she believes he can, and he gets help to understand why he hurt his ‘best friend’ as he said, they can overcome this, it’s their choice, just as having children is. I don’t think she would be giving things another go if she was planning to get shot of him eventually, she loves him, and I believe he loves her. Nothing can undo the past, but you can change the future. The problem here is the stalker and abuser, they need to deal with her and shut her up, so they can focus on what they want to do moving forward.
