There is a lot of great advice here, some of which I also wish that I had when I was in a similar situation myself. The difference is that throughout the entire relationship my ex worked sporadically and even when he did work, he would find a reason why he could not continue.
He would take his friends out on his jetski, entertain, invite people over at all hours without any consideration for me or costs. I finanically supported two of his business ventures and moved states to support his re-entry into the workforce which failed.
Eventually the marriage ended due to two affairs that he had and the bitter part is that I was then legally obligated to pay support!!
Talk to him about it now and see if there is an amicable resolution!
if he is collecting unemployment right now, and wants to be done with school and have an established career before you two start creating a family together, then he should be taking steps to get those goals out of the way. why isnt he going to school now? even if he gets just an associates degree, thats still 2 years of school.. its going to be a while until he graduates and finds a career that will support a family. you should deffinitely talk to him about your concerns.. it sounds like the two of you are on seperate pages when it comes to the future. if you try to talk to him and he doesnt get it.. you'll just have to keep on it, until you can get him to understand. you both have wants, and if you cant compromise and come to an agreement then you might need to start re-evaluating your relationship, and what it was that brought you two together in the first place.
you dont want to wait too long to address this situation, because silence and time is only going to make it fester inside of you and damage your relationship.. causing you to resent him and feel unappreciated.. becoming more bitter and hurt, until it might be too late.
Hey! I really think that the best thing you could do is not focus on the 'having children' aspect just yet. There is absolutely nothing wrong with being bitter towards him, in fact that's perfectly understandable. But you are allowing him to get away with it and he will probably continue getting away with it for a while if you don't put your foot down. I agree with lain's advice
