Laura,
I sense that you might already be feeling that this relationship might not be worth the effort for the long term. You have a lot going on right now. If he isn’t being supportive in certain matters and you don’t want to make an issue of it, then you might be harboring some resentment.
Only you can decide if you want to continue seeing him. If you really need some time to think, then just don’t be available the next time he asks you out. I have the feeling that he won’t get the hint though. I sense that he is satisfied with himself as he is.
May you have a very Happy New Year! Once you have a clearer direction regarding work, etc. things should be easier.
🙂
