Zoe, my heart is absolutely breaking for you right now. I can’t quite imagine what you must be feeling..
I think he is a coward for not being upfront and honest with you about anything. Had he been upfront and honest about his intention to move forward with his life (with or without his new fiance) he wouldn’t be having to explain himself right now. I think his behaviour is that of a cowardly, unsure and unsettled man and quite frankly I feel sorry for his wife to be as the foundation to their relationship is clearly built on lies. This is purely a reflection on him and who he is as a person.
I know this may be easier said then done however I don’t even think he should be given the opportunity to make that call. There is nothing that he can say or do at this point that will even remotely justify his actions. Nothing.
I know it hurts, I myself am struggling with a break up at the moment, but I do think perhaps this is all the closure you need… I mean how much clearer can he make himself than deciding to marry another woman?
My thoughts are with you in this difficult time!
