The couple, who have been dating since 2011 after meeting on the set of 'X-Men: First Class' four years ago, have found a way to make their long-distance relationship work when they both have busy schedules.
Speaking in an interview with the new issue of America's Marie Claire magazine, Jennifer explained: "When we're busy, we agree to mutually ignore each other. Not completely, but neither of us gets mad when the other doesn't text back or call. Life's super-busy. Obviously you know what they're doing, and you trust them.
"We're so young that it would almost be like if we lived in the same city, what would happen? We'd be living together. At least this way he's in the same boat as I am: We can both go out and have our own lives and know that we have each other."
The 23-year-old actress admits their relationship can be a struggle from time to time but she believes it's important that they lead their own separate lives.
She explained: "It's hard [ when you're both working]. [But] it's important to keep your individuality when you're a couple and keep your own life."
