F, I'm sorry this is happening to you. Have your h always been this way? Die something happen to him within 18 months of getting married to you?
This may not be mlc at all, but his true personality. There are some people who have this "never happy attitude". They are thrill seekers who are constantly getting their high on new things, new adventures, etc. Once the euphoria is gone, they tend to drop the item and move on to something else. This can also apply to marriages and/or relationships as well.
Can you tell us more about him and his personality? It could very well be an identity crisis and he would be just about the right age for that....but we need to know more about the situation in order to try to help you along.
For now, take care of yourself, protect your assets, set up a separate account and take him off of any credit cards that you have. If he's out there doing the "thrill/rush" seeking things, he's self-medicating for some reason and you do not need to be pulled down into his financial ruin, if it should come to that.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
