I have never posted to you before but have read most of your Sitch. Which was good for me because now I know what not to do. Going to church and reconnecting with your Religion is excellent. I have been a practicing Catholic my whole life. But God does not do the work for you. You can go and pray all day long and if that is the only thing you do it will not work. God gives us the tools and the guidance to do what we need to do but we still need to do the work. Come on man you really need to man up.
I rarely post to anyone else on here because I am still new and don't want to give wrong advice but I do know that your W will not see you in any good light if you continue to do what you are doing. Get back to counseling to control your emotions and find stability. Get back to AA so that you have some more direction in your life. At least going to AA will give you something to do. Talk to a Priest about things good. Be good to your kids and enjoy the time you have with them. When they are gone don't concentrate on them not being around work on things that you can do and what you have control at that time.
