Just prepare yourself a little bit before entering Thailand again, for example, buy a bus ticket out of Thailand, have some money to show if they ask for proof, and book a hotel for the night or so. And I think you will be just fine. Worse what can be they will tell you not to try to enter without a proper visa next time
if they decide to freeze your account they won't care whether you will renew something or not they will freeze without any explanation maybe your time still doesn't come
Robert Kleinark and marriage in Thailand is not so simple you will spend a lot to prove that you are really married not for a visa, you must do a party in her village so you will pay a minimum 100k THB
