Tip one: Grow together. Your dreams may change, and you may grow, but you do not have to do it alone. If you want your relationships to last even as you grow up, be sure to do it together. So, you leave behind your dreams of dropping all responsibility and moving to Hollywood to become an actor or actress, but you keep dreaming, and find new dreams that you can share with your significant other. This is how you grow up in a relationship.

Tip two: Make a point of staying involved in each other's lives. As you grow up your interests may change, and your way of handling things may change as well. However, one of the best ways to make sure you do not out-grow your relationship is to stay involved in each other's interests, no matter what they may be. You may no longer love the things you loved in the past, but that does not mean you can't love the new things along with your significant other. So, talk about your day, stay involved with each other, have fun together, and never forget to do things together regularly.

Tip three: Keep some of the immaturity. A relationship is going to be work and responsibility. However, you should include some fun. As you grow up in your relationship you need to make sure you do not leave your fun, spontaneous, and immature self behind. So, make sure that you have a bit of immaturity in your relationship, but make sure that immaturity comes out as funny stuff, not as immature fights, etc.

Tip four: Practice the qualities of a healthy relationship. Healthy relationships do not happen by sitting idly by and hoping for the best. They require work, and effort on your part. If you want to grow up in a relationship, and allow the relationship to mature, you have to work at it. You have to be willing to communicate, to work through problems rather than run from them. Practice active listening, practice working together. There are many things you should do to have a healthy relationship. You have to work on your relationship so that you have a healthy relationship that can withstand the storms in life, even the ones that are caused by growing up.

Tip five: Don't use cop-outs. Relationships are hard, and there is always a ready excuse for why things did not work, or why you couldn't stay together, but only you can make the excuse, and justify it. So, instead of saying you grew apart, don't let a cop out win, and make sure you do everything in your power to make sure that does not happen.
