Sane..if he's interested in men, you will see sign of him eyeing guys easily...if it's cross dressing, then he also need a psychiatric help as it will lead to split personality n that is dangerous cos it's call Bipolar n these category of ppl , u nvm know when they snap ... If sourapple u r a Christian, that's easy cos prayer will break it otherwise pls seek professional help... Ur hubby will not want to go, so u hv really think of ways to entice him to seek help...if he snap, he can endanger you n your kids n anyone near him...its a ticking time bomb... God bless
