I believe my husband is gay. How should I confront him?

My husband (34) is a great father. I'm not really attracted to him at all but he's a great father. <br><br>He's always super sensitive and I just feel something is not right. He gets upset at not being able to be himself. I know there must be something and it's just weird to me. <br><br>He's freaking out about what the future holds for our daughter and he's showing fear to live past 50. <br><br>I'm convinced it's because he believes he's gay.<br><br>Anyways I just don't understand why he married me if he thinks he's gay. He's been depressed.<br><br>Also the last time we had sex was months ago and he never initiates but he will let me initiate.<br><br>Anyways how should I confront him?
