You are 23 year old girl and you are not married but you have been 3 times and want to be more and more when you will get married did your husband will get know that m before?

yes he properly will no that you have been before as usually when you get married you have to produce a divorce cert if married before. its best to be honest then keep this from him as it could turn out worse if you dont. id also advise that you wait a while and be sure your ready for another 4th marrage at only 23
