There's also the matter of sex. If you've been together for over a decade or longer, the passion may have waned to the point where you feel like flatmates.
As much as I hated the idea of that at the time when it happened to me, it was the cold hard truth that we had gotten to the point where it was just loving cuddles all the time. We were more like cuddly cats, cosy comforts, eating treats, familiar.
Too familiar.
His body felt like my body. There was no electricity when we touched.
With current partner, I've been with him longer than a decade and my God the electrics are still full on Christmas lights.
Sex is important to me.
I can't imagine now looking back, spending another twenty years with that "cheating" ex and sex being part of the relationship. It would have become more cosy and more sexless until we both turned into teddy bears in pajamas. A kiss on the cheek goodnight. Flatmates.
What's shit is that we marry and make financial commitments and arrangements based on the most transitory connection of all, sexual attraction. And once the pressures of real life hit, I sometimes wonder how many people would just walk away if they didn't have to financially stay or if they didn't feel guilt for leaving.
It's grim isn't it... reality.
