I honestly believe you can never tell if a relationship is going to last. In my own marriage, which is going on 14 years, I don't think of it as 'I'm going to be with this person forever.' Instead, I think of more like, 'I'll probably be with this person for the next six weeks. Then I'll re-evaluate.'

The thing that I think is the most important is taking moments to express your appreciation to your partner. A thank you or a quick kiss can go a long way toward affirming your relationship and commitment to each other. That's not hard to do even when you're juggling insane careers and three kids.
