What was the point of getting married if you are unable to uphold your vows? Was your marriage something that you jumped into relatively quickly?
What were the circumstances of your breakup with the ex? Because there is usually a reason for breaking up (unless it was just to get married).
I think you're more homesick than anything and if you and your wife don't find some sort of compromise, you're going to end up moving back home anyway. However, I wouldn't consider going back home because of an ex ... You didn't marry her before, so perhaps it is unlikely you'd marry her now.
In any case, a long, deep conversation is much needed between you and your wife. And you have to let her know how badly the living situation is bothering you. If you're not willing to stay and she's not willing to move, then perhaps it IS best that you part ways.
