OIN when you say crap like that to her you JUSTIFY her LEAVING... It is making your case WORSE not better... why do you resort to giving her nonsense and ammunition?

I would have just told her

Running away isn't going to make either of us feel better in the long term... no one enjoys a failed marriage on their conscience...

And THEN I would turn and walk away...

More to the point, why are you getting INTO these conversations in the first place, DR makes it crystal clear you should AVOID relationship talks... and your SPOUSE WILL PUSH them on you... AVOID them.. you seem to walk right up after them like ice cream...

it is NOT going to improve your situation to discuss your relationship with a wayward spouse.. you just give HER ammunition to LEAVE

Stop pursuing her and stop the marriage talk... if you DO get sucked into saying SOMETHING.. say something CONSTRUCTIVE to cause her to DOUBT divorce... telling her "I just want you to be happy" is NOT helping your case... it IMPLIES

Divorce me, you will be much happier and you have no reason to feel any guilt...

that is what she hears when you say "I just want you to be happy"

You are just putting a bullet to your big toe and firing the trigger...
