Boyfriend struggles

So I've been with my boyfriend for over a year now and I'd like to think we're pretty serious. We have a dog and are looking at apartments to move into within the next year. But in the past 6 months he's broken up with me 3 times and then immediately taken it back. I love him and want to be by his side through his successes but I don't think he knows what he wants out of this relationship. Ladies I'm in need of some help!!
