So sorry you're going through this. I hope you have some friends or family you can lean on during tough times like this. Even for men, it's important to have support.
I would echo what everyone else has said, all good stuff.
What I've learned from my marriage/separation/divorce situation: It takes two to build a marriage. One spouse can destroy it single-handedly even though most of the time both are involved. But it definitely takes two to maintain a healthy marriage.
So my two cents here: If both of you are willing to work on yourselves and find a way to come together and support each other, great - keep at it. Otherwise, don't waste any more time. Life is too short.
