Do not reply back to his texts today. He's telling you about the free legal lawyer dropping him and him screwing up his unemployment to get sympathy from you. Poor baby! You aren't his mother and he certainly fired you as a wife. Now, the real world is setting him and it's on him to find another lawyer. Whatever you do, do not help him figure things out on his end about the separation/divorce. That is on him, i.e., he walked out, he's moving his stuff out and he's the one having the affair. If he can do all of that, then he can put his big boy underwear on and figure his life out for himself. Any questions that he poses to you about the legal paperwork, direct him to your lawyer. And, .....no is a valid answer to questions that you don't need to go into depth w/him. Also, when in doubt, do nothing. Sit for a bit and then the answers will come as to what you need to say or do.
Keep the focus on you as much as possible. I do understand why you continue to think of him and post about him, but for the love of the man upstairs, please try to let him go, emotionally, mentally and spiritually.
Also, don't put a time limit on what will or will not happen in a year. Let that thought drift away. Sometimes it may take more than a year to reconcile and then again, after a year, you may decide you are far better off w/o him. So, drop the time line...it's putting undue pressure on you to try to "win/nice" him back. It won't work. Let him go!
KEEP THE FOCUS ON YOU!!!!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
