My husband isn't interested in intimacy?

The first question you should ask is whether sexual intimacy has continuously been a part of your relationship with him? If the answer to this is no - then this current situation shouldn't be too alarming - although it is still disturbing, I understand. However, if the answer to the question is yes - then some action should be taken to preserve your relationship with him - such as couple's counseling. And if you have had continuous sexual intimacy with him before this - then you must also ask yourself honestly if it was ever consistently better or different from what it is now. To be honest, my take on what you're telling us here is that he is admittedly depressed. It is a known fact that depression decreases a person's sex drive. And could also make him more withdrawn. If this is the case, then you are not the problem most likely - the problem lies with his own personal issues which could have something to do with anything ranging from his current job, his parents, bills due, etc.
