because they are attracted to them and want to have an affair
Technically, you don't 'become' lesbian. You can be bisexual and have married a man and have been attracted to them, but also have feelings for women. Or they could have lied while they were married and just pretended to be attracted to men. Or they could not have realised that they had the capability to be attracted to men, and only realised it after being married.
that just means that the lady is cheating on her husband to be with your husband
