You know the phrase 'lucky in love'? Well, it may apply to the two of you! You were attracted to each other from the start, as a flower turns its face to the sun.
There is a strong, almost magnetic pull between you, and you both just...click. You both just naturally slip into your roles within the relationship, with little angst or trouble of any kind. Either your friends and families accept your lover in your life wholeheartedly, or it doesn't matter to you whether they do or don't -- because you know you're great together. You've got similar ideals on romantic relationships, but you probably don't even have to talk about them much or try very hard to make sure they match up. This is the kind of aspect that will help make a relationship effortless. You just fit together really well, and you have such similar ideas of where you want the relationship to go that it feels to both of you as if it's fated to be. For both of you, a good romantic relationship is one that you can rely on; one that will give you comfort and strength, and, of course, fun! You both see it as essential to a good life. The only trouble here might result from having a hard time remaining individuals, since you identify so strongly with the relationship; but in general, this is a great aspect for a long-term commitment.
