I signed up on this site to support you. I've been reading your story for the last 2 weeks and thought I need to give you my testimony. I have a strong belief in faith and know the battles you are fighting. I've been in your shoes, I know the demons that you are fighting, the tears, the depression, the hurt, reading into every little thing that she says, etc...
My wife had an A in 2008. I did everything to get her back. Acccording to this site all the wrong things. One thing I had is my faith. She left the house and moved to another state with my S8 and S4 and the OM. I too was in school finishing up my degree at the time she left. Sitting in an empty house, losing my Fam, Dealing with those emotions and the tremendous loss, I luckily pulled C's in all 4 classes I was taking. I'm an "A" student.
Talk to God, he is the answer. DB is a great site for giving you some direction, but always remember only you know what feels right and feels wrong. Everything that you are told no matter who it comes from is not always right nor the right thing to do for your situation... I'm not trying to confuse you just trying to help (to be continued, on my way home from work)
