Strong and meaningful relationships mean that you are willing to compromise with that person, regardless of if it's you or them "changing."
It's the attitude that people have changed from "it can be fixed" to "just junk it, it can be replaced". I think this starts early in a relationship, and merely builds over time.
Yes my marriage can be challenging at times, and I am not 121 or even flying full time, but I do work a lot of hours, and can be away from home. I would like to really find the "perfect" one and call BS.
I went into this knowing that it takes work, there are many great things, and a few not so great, but what are you going to focus on? Yourself? Your Partner? I would be willing to put money down in these failed relationships, that it has been awhile since one or the other hasn't done something nice, and meaningful for the other, rather just keeping to their own personal interests and leaving the other person out of it.
