Something is very wrong with your wife. I wonder if she developed depression or PPD after the birth of your son and, without treatment, it hasn't gone away. She doesn't want you to touch you and finds you disgusting for winking at her and telling her she looked good. She doesn't want sex. None of this is normal behavior. She needs to get therapy to find out what's wrong with her.

You really can't go on in this marriage like this. You are basically roommates and that's not good. You are going to have to make it clear that she gets help because she isn't acting like a loving and caring wife or the marriage will be over. Sadly, that seems to be where you are right now.

Also thanks!

Your friend has no responsibility towards this baby until a DNA test proves the child is his. Your friend requested proof and she hasn't responded. Until she does, your friend doesn't have to do anything. He might consider contacting a family law lawyer and asking what steps he needs to take over this situation.
