There's no easy recipe for a long-lasting relationship, but you've found some of the main ingredients. Chemistry is definitely a great foundation. Then you add some trust, communication, and respect. Of course, a dollop of humor and a generous amount of romance make it much more satisfying. There are many more things you can add to make it better, but that depends on the needs of the relationship and the individuals. The two of you have clearly mastered some key elements and seem well on your way to building a loving, long-lasting relationship. If, however, you have some doubts about him, or if this relationship isn't truly what you want, listen to your inner voice. "Forever" shouldn't be taken lightly. Try to explore your fears and concerns thoroughly. And, remember, if he's not "the One", that's okay, because you'll find someone who is even better for you. It's a win-win situation!
