Also keep in mind that temporary ordination is a very normal thing in many Theravada traditions. Having small periods of manastic life interspersed with lay life is very typical in Laos and Thailand, and many that i"ve spoken to have found it to be a very rewarding path (this obviously gets more difficult if\when children enter the picture but is still very doable).
Second this. Don't do anything drastic until you've spend some good time in a monastery, I'd say at least a month.
I knew a guy in the same position you're describing and he opted to become a monk. That was three years ago and he's still ordained. There's no real going back for him now. Even if he wanted to return to his woman, it wouldn't be the same now I'm sure. And that's assuming she would take him back, which seems unlikely at this point.
Be careful! A good lady is hard to find!
