Very sad. Sorry, UT.
But here's the thing - after all that time of being a part of something else, you
need time to be yourself again. It sucks not having your partner there to chat with, bounce ideas off of, or just sit in silence, but you're clearly healthy in the head or you wouldn't be in mourning at the moment.
So, PLEASE don't try to fill the temporary void with anything else but yourself for at least six months, longer if possible. When my ex and I broke up after 11 years, I was just... broken, for want of a better word. I felt like one of my lungs had stopped working, or something.
But I learned to breathe again. And in that learning process, I discovered that I was actually a better, happier, healthier person on my own. I realized that
I was what fulfilled me, and that whatever came along in the form of another person/relationship would be the
icing on the cake that was me.
BE THE CAKE!
