Take however you want to take it, but don't get sucked into the woo-woo and start believing your dreams predict the future. Your dreams express feelings, that much is clear. You were worried about him leaving you, at a time when the marriage was troubled. Now you wish you could get that loving attention from him, so that's in your dream, too. It's not a prediction.
It wouldn't be so bad to think such a nice dream could predict the future, I know, but you know that isn't true--and if you dream of him leaving for good tomorrow night, it'll be ten times worse if you've allowed yourself to think of these as predictions of an objective future.
Try to enjoy it for what it was--you maybe felt desire for him and, in your dream, he returned it. That's a long way off for you, judging by what you've written about your situation, but it could still happen.
