I know this is very difficult right now to wrap you arms around we have all been there.
Right now she only sees the bad in the marriage (that will change) and you only see the good (that will change).
You have no children so this will be an easier break. Read my tagline and focus on that and the rest will work itself out.
You each are on a journey and your paths may or may not cross again one day.
Oh I know and accept the bad in the marriage. Her part and my failures, and sins of commission and omission if you will.
I was under no illusions that marriage was all good-times, party time. So I expected some of this and I certainly expected rough times. but this crap is on a whole 'nother level & completely void of reason and logic.
