My friend, please take a huge breath and let it out. Right now, the clouds appear dark for you, but you don't know what the future holds for you and your w.
Your wife needs to grow up and it's going to take some time for that to occur. Yes, she's disappointed and upset right now, but what I have observed w/mlcers is that they can't stay away for very long.

Breath and let it go...there is a reason for everything that happens to us. God has a way of showing us what we need to know and sometimes, it's good and other times, there is pain involved. Step back and allow nature to take it's course for now.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
