Understand that you probably have a year or two of work ahead of you. It needs to become part of your lifestyle, not an effort to win her back. Do you understand that first sentence? You are going to have to learn to be patient, this is something you probably don't have much of, if your job was a stress filled schedule tight area.

Your probably having some anxiety attacks, hardly sleeping or eating. So make sure your taking care of yourself, and get some exercise, even if its just doing some push ups/sit ups in the morning or evening.

Understand she might be all over the place for a while, try not to bring up and R (relationship talk), keep your conversations about finances and kids only. NO pressure. If she brings it up, its ok to LISTEN and validate her. Try not to interrupt, keep eye contact, and never interject your opinion right now. A good response(s) for now will be "I understand how you feel" and/or "That's something im working on"
