You have (given) no information to expect an affair, so please don't worry about that at this point.
Right now...detaching...as puppy suggests, will help you to work on the things you need to work on ... to heal yourself....And that is so important.
We're here to help you detect solutions and to offer support. Most importantly, is taking care of your depression, though.... I don't know which came first...your depression or her leaving...and I don't know lots of things about your situation, like your wife's complaints....
This knowledge is important before you take any advice from anyone here. The only thing you can be sure of right now .... is the more you openly do to actively try to save the relationship is most likely to push her away. So console yourself that turning inward and healing yourself is the BEST chance you have at working on your marriage.
We often feel we have to have these things in place to be happy. But already being happy really makes a marriage start out more smoothly.
I know it is really hard. We're here for you.
I don't want you to think about an affair for her....but other than that...Puppy is an amazing man and gives great advice...he is a leader on the board.
Keeping you in my prayers, sg
