Swimming....no one can answer that question officially because even HE has no idea.
So here's my answer that I want you to take and go with it. This is the official answer, OK?
He's confused. Sometimes he does want to divorce you. He wants out. He wants to burp and fart and drink beer and not answer to anyone. He wants to watch football and eat pizza and leave the empties all over the bachelor pad.
Sometimes he wants to just hold you and be married to you forever. He wants to snuggle. He wants to play. He wants to come home to dinner with his FAMILY of you and your kid. He wants to help around the house and play with the kid. He wants to go to sleep next to you.
So guess what? You better just chill out. The more you freak out, the more you give him opportunity to say "You aren't my family, I don't want to be married, it's over, I'm leaving" the more it becomes real to him. So STOP. Do you understand me? You can turn this around so he wants option two more and more and option one less and less.
