For now TB, keep the family out of it, you and her don't need the added pressure.
I know how bad you want her to work on the marriage right now, but im not gonna lie to you, that's NOT gonna happen. You need to get that out of your mind and NOW. That comes off as pressure and controlling. Both will push her away faster than you think.
I know the absolute hardest thing to do in this early stage is to detach, it feels damn near impossible, but its EXACTLY what you HAVE to do. ANY talk about the future is a BAD idea right now, and the near future.
Why are you roaming a 4 bedroom house alone? Cause right now you've let your emotions take over in a negative way, if you continue to do this your also making things worse. STOP looking at facebook, it will get you no where and prob even make things worse as you will start thinking for her or about her. Don't project what she's going thru, cause you have no idea.
Take care of yourself, sleep (get some melatonin for just before bedtime), exercise, and most of all EAT. Get out of the house, even if its a walk around the block for now, join a gym, pick back up or start a new hobby, hang out with friends. Keep yourself and your mind busy, worry about the only thing you can control right now........and that's you.
Your in the first week of what might be a year or so of work, going to have to learn to be patient. Trust me, I know how impossible that sounds, but you have to at least get started.
Keep posting, try to explain why your here exactly, what went wrong, and what you think you could have done differently. Give as much information as possible so the vets will be able to give better advice without having to ask a million questions.
