You probably slip naturally into a commitment, without even noticing or questioning it! You two are really similar in the ways in which you approach a love affair, not to mention how you go about finding success in your career. The two follow similar paths, as a matter of fact, for both of you.
You're both driven and hardworking, and you're willing to put in the effort if you know the end result will be a success. That's just how this relationship goes. It isn't necessarily all fun and games; like every relationship, you encounter your fair share of trying times. But through it all, you know that you can rely on each other, that you have a great and solid foundation that will stand the test of time and trouble. You're loyal to each other, and you both know it. You trust each other to treat the relationship, and you, with respect. You both have a sense of duty and responsibility regarding the relationship, and you live up to whatever you see as your responsibilities. When you make that type of commitment, it seals the deal between you, even if it's just verbal. Moving in together or saying those magical words -- 'I love you' -- are tantamount to marriage for both of you. Since you're both this way, you blend together well. So enjoy this serious relationship! It might just be the One -- the one that lasts into the foreseeable future.
