Whoa...slow down there, cowboy...
You are not even divorced and you are already getting ready to jump into Thailand for your next wedding.
At the speed you are going, are you sure you are really serious about settling in life?
Are you really sure what you see in your future Thai wife is not the same with how it was before you got married to your current wife?
If you just want to have some "fun" you don't need to get married.
If you and your future Thai wife are serious in a true marital and familial relationship, your future Thai wife can help you ask the relevant authorities about what you both need to get married.
