So here is my not so optimistic response: I admit that I am probably going to sound like a heartless cynic but…I honestly believe that you are going to lose attraction to anyone you marry, or are with for a long time, even a Barbie look alike. I suppose I could go into this more, but I’ll just say that there are different kinds of love. That sparky attraction part of love goes away and is replaced with a different kind of attraction over time. I have been in two long term relationships. The first lasted about 3 years. The second has just now hit 3 years too. I struggle constantly with finding the balance between getting the stimulus, excitement and “attraction” I need along with the comfort, stability and security that I also need from a relationship. It’s something I never would have thought would be an issue if you had asked me at the beginning of my dating life. Maybe for most people it’s not an issue and I am odd. But I remember when i broke up with my ex my dad said to me when i was crying heartbroken on the ironically named loveseat in our living room, “Romantic love is Nature’s trick.” It is so easy to be attracted to someone and to fall for them and think that they are great, or even “the one.” But over time we lose this attraction and are sad and think “I will never love again.” But we are indeed “tricked” again. The cycle continues if it is Romantic Love that we prioritize in a relationship. But Romantic love is not the only type of love or attraction. In both of my 3 year relationships, the attraction and dynamic has changed. The things I was attracted to at first are not all of the things that I would say I am attracted to now. I have never gone beyond 3 years, but I imagine that as time passes and as the relationships changes even more, the attraction will change with it. I hate, again, to sound like a romantic-less cynic, but attraction, love, and a relationship/marriage, which are often grouped together, unfortunately are separate entities. Having one doesn’t give you the other. Just because you are attracted to someone doesn’t mean you can love them. Just because you love someone doesn’t mean you can make a relationship or marriage work. Just because you are no longer attracted, or even if you no longer love each other, it doesn’t mean the marriage can’t work. So maybe I have just been jaded too early by the broken relationships around me, but I believe that you WILL lose that initial attraction that probably draws you to many girls you meet. It may not be right away, but time is time and nature is tricky. What happens then? Hopefully there will be enough going for this girl, and for the lives you have built, or are still trying to build together, that this physical appeal can evolve into a different kind of appeal that will keep you interested. Not impossible. Good luck!
