Very true, very possible. If you are sure she's pro marriage then stay with her. Could you possibly see her alone and let her know you thought that crap sucked? That basically you want to cut back on his opportunities to say such crap? Or maybe find out what the heck she was trying to accomplish with that?

I think you are doing great. You aren't falling apart or groveling or making a fool of yourself which is very hard in times like this.

Stay strong
