I am looking at the start dates on the situations of those of you who are asking about dating, and only one thing comes to my mind here.
WTF??????
You guys have been at this not even a full year. Your WAS are obviously confused and lost right? It does not give anyone the justification for finding someone else or dating. You still have an obligation, not to your spouse, to yourself to maintain the commitment that you made and not make the same poor judgment that your spouse did that has led you here and devistated your life.
Let me throw this out there. Let's say you did go "date", and let's say 6 months from now your spouse comes out of their fog and it truly was MLC,how exactly are you gonna justify that you gave up on them and strayed?
You come here to try and save your marriage, if that is what you wish to do then stand for it until such time that you don't have to ask yourself if it's the right thing to do or not. Simple as that.
