I'm writing this as I'm waiting for my bath water to raise to a tolerable level(hello, its December FGS!) and thoughts of you and me and our future creep into the deep abyss of my consciousness. Will this last forever?
I think its normal to think of things like the "future" especially if you're in a relationship that you would want to last. If we live in a perfect world, everything would've been easy. Everything will go according to what was planned. Heartaches, disappointments, and hardships would've been avoided. But we live in an unperfect world and two unperfect individuals trying to make it work has a lower chance of working out than winning the lottery.
In the end, I'm comforted by the idea that we are both willing to make this work. I believe in you. I believe in us. We'll cross the bridge when we get there.
