Just my two cents…

You are right: all couples go through hard times and that shouldn’t be the main reason to end the relationship. I don’t think he can be blamed for being unemployed with this current economy (not saying that you blame him). But apparently he doesn’t even try getting a job or pursuing a degree in Psychology (as he said he would do) and that is not a good sign to me. It seems like he is comfortable with the whole situation the way it is right now.

I don’t think you can expect much change from him. I wish you strength and wisdom in this situation.
