I don’t feel uber-qualified to answer this. Rather, I just want to join in the discussion with some of my favorite people.
My short answer is that my long term relationships have gotten progressively longer. And easier. I think the why is that I’ve managed to apply better criteria as I’ve learned what to look and look out for.
I may be missing some key lesson, but I think what it comes down to in the end is that you love yourself more. Or maybe that there had better be plenty of room for you to love yourself. What I mean is that the person you are with is naturally inclined to lead, follow or get out of your way in the same direction you are going. You want to achieve some things or build on a foundation. You can share that space with someone who is supportive or who isn’t. Who shares your enthusiasm or doesn’t.
Of course, you have to know what that plan is. Or you don’t. To me, knowing is boring and scary, so whoever gets me has to deal with a “not knowing” person. Undoubtedly, this is draining. I seem to find “rescue/take care of me” persons (although maybe we are all that way). It’s gratifying for a while, and then I want my energy back. I love myself more, even though that self is ill defined.
The concept of “love addiction” might be worthwhile to understand. I don’t think you’re that way. I only mention it because you are confused about what is normal. In a nutshell, it is a compulsion to seek the pleasure of romantic love in lieu of all other aspects of life that bring meaning, such as relationships, community, principles and spirituality.
Being smart, by the way, is actually a hinderance for LTR prospects. It puts you in a smaller pool, and it makes you more picky. There’s research on this which I’m sure you can find. “Average” people are more content to put up with a wider variety of crap from their SO, according to the study. I think.
Another study finding… successful couples do not avoid arguments, but do argue in a respectful and caring manner. See PBS’ “This Emotional Life” episode 1.
When I was 25, or maybe even before then, I took some time to articulate my values a la the Franklin Covey method. what came out was a very clearly defined picture of a guy who lived a rich and full life by maintaining relationships and practices that were important to him. I was able to pursue some of that in a place that supported me, Seattle, but have since been waylaid by the significant derailers that you already know about and for losing faith or understanding in the process of the universe rewarding your effort. While my values have shifted somewhat from that original template or draft, they are basically the same. Now, I certainly have myself to blame for failing to try earnestly, but guess how many of my LTRs have really supported me doing these things? Guess how many have kind of been in the way? Guess what I think I might do someday when I get my life back, and it supposedly isn’t bogged down with things that are the opposite of what I wrote down 10 years ago?
In no particular order, my last observation. Some people are better capable of doing a LTR than others. Some haven’t worked through their trauma, and their comfort zone is to recreate their trauma in their relationships. Again, they compulsively seek to reenact the trauma in lieu of pursuing meaning.
25 yo, find yourself. Be yourself. Approach others as an opportunity to learn something. Share with them, but when it’s time for your train to pull away from the platform, get on the train. Have faith that you’ll meet a likeminded traveler and say yes when you find him.
“him” autocorrected to “Jim.” might be a sign. ;-)
