I agree...stick to the issues at hand. Do not agree to anything without speaking to a lawyer. Just because you speak to a lawyer doesn't mean a divorce at this time...you need to know what your rights are and how you are going to be able to take care of your children.
I would most definitely stay in my home. If she wants a separation, well...she can leave or move into another bedroom...you...take the main bedroom.
Listen to the others...less words and just stick to the facts. She doesn't care if you felt rushed or not.
Keep the focus on you and your children. Your children need to know that you are there for them.
Come here and ask questions and above all else....do not agree to anything at this time until you have sought legal counsel.
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.
