Everyone around us is fighting their own little war. I've felt similarly to the writer -- I moved out of my childhood home the day after graduating college and started work that Monday. I only moved 215 miles (NYC to Boston), but it felt a world away, especially considering most Americans live relatively close to where they grew up and 215 miles in Europe goes a long way.
I've made and abandoned friends at almost every stage in my life. I have no idea who will be the best man at my wedding because to be honest my brother probably isn't up to the "responsibilities", but I have no alternative.
I now live on the west cost, a tough 6 hour flight away from home. I visited my family this Thanksgiving and am noticing so many changes, people are dying, babies are being born, my cousins who I've always viewed as children are about to graduate college. It's tough being away from home and not feeling like I have roots (I'm considering a move to Seattle or the Bay Area in early 2019), but at every step I've justified my actions because the next step always came with a significant pay increase and more career opportunities.
This January will be my 13th anniversary with my high school girlfriend (soon to be fiance). I can't describe how valuable it's been to have someone so close in age (I'm 3 months older) that can relate to the things that I'm going through, and who has my back, and knows that I have hers. Things haven't been easy, but it's become so much more than a girlfriend/boyfriend relationship, which is why marriage is in our future.
I've met so many fellow millennials who are serial monogamist or date freely, I don't judge them at all and at some times have felt a tinge on envy, and these folks may have a friend or family member who is to them what my girlfriend is to me -- I guess all this is to say that in today's society I just don't know how we can traverse this reality with at least one person who you are tightly integrated with. It's just too tough out there.
