The chemistry of a stable couple - Or lack thereof

I don't know what bonds us anymore.
Whatever we used to share we now enjoy separatly.
You used to admire that I lived a packed life, now it tires you and you resent me for not making more time for the things we said we'd watch together.
I used to love going out with you, meeting friends, training, I used to love writing with you, talking for hours, now I resent you for being such a home bird.
I wanted to listen to this saga with you. I discovered it on Tumblr and wanted to share it with you. You ran away with it because I didn't have enough time, and now I resent you for that. It feels like you stole it from me. I know, it's irrational. Nothing prevents me from listening to it on my own, but I can't help but see in it a symptom of our relationship: what we could have shared we don't. Because I am too busy. Because you are too lazy. Because I am never in the right mood. Because you can't wait.
I want to go running but you hate running. I want to go swimming but you hate swimming.
Our lifestyles are similar and yet so different. I hate noise in the morning, you watch videos. I wake up early and I am active quickly, you're not a morning person.
At which point are we too different to make a good team? I am afraid of those thoughts because I know them too well. I've been there already and I don't like those clouds on the horizon.
At which point are we too dysfunctional to function together?
At which point are you going to realize that you have no reason to love me anymore.
