I didn't go back to your older posts, but are you saying that your husband has had multiple affairs going all the way back to dating? Then from there he actually lived with the OW and her husband? Topped all off by the fact he hasn't given you any financial support and is using savings as a form of control?
TIME TO SEE A LAWYER! Seriously! Your husband is responsible for his have of the financial situation regarding your child. Such childish behavior on his part is garbage. Hell...even my wife in LALA land makes sure the bills are paid.
Keep up the mysterious behavior...he doesn't like it...so what! He has left, he has cheated, he has tried to control you. It sounds almost abusive. I think you deserve more...you need to start thinking that also.
