Re: I miss my wife. I need her back
Marriages can work with people away for extended periods of time, but it's far from ideal and when things are shaky it's almost guaranteed to cause a wedge. If you want to fix your marriage, you need to be there to make it happen. You can't fix it from the other side of the world. I don't think you can in your particular situation. You can pray for your marriage while you're there, but there's nothing you can do yourself.
My recommendation is, if it is at all possible in any way, return ASAP. If you can investigate your wife's activities online or on her cell phone via a keylogger or voice-activated recorder, do it. If you find nothing major, decide to trust her and then be there for her for a while to repair your relationship.
Sometimes there is no substitute for spending time together.
