At least I have her though..
I am early 30-something male in the U.S. and on the fringes of ending a 4 year relationship with the girl I live with. I don't want it to end.
But here's the thing.. I didn't want it to BEGIN.
She aggressively pursued me when we first met 4 years ago, and I was into another girl but she wasn't into me, so I said "what the h***, I'll hang out with her" and then.. something happened, she got to me. I honestly didn't think it would become anything significant, even then. But it got out of hand, and just 4 months after we met I found myself moving in with her. We were together ALL the time. But something felt "off" about it all. It was just chemistry I guess. Anyways, I got bored with her after about a 18 months and started ignoring her, treating her badly. Nothing really bad, I never laid a finger on her, but I threw my rock-star temperate tantrums and destroyed things in the house, even so bad once the neighbor called the cops because I destroyed both our flat screen TV's and put holes in the walls with my fists. I am an ass. I ended up paying her for everything.
Fast forward 4 years later.... NOW I'M THE ONE WHO DOESN'T WANT IT TO END. It's so sadly ironic, pathetic and bizarre, but she's making me leave (we live together in a house) - she wants me out in just days. And I keep thinking of that guy who took it all for granted. All of it.
So my point and advice is:
APPRECIATE THE THINGS YOU HAVE BEFORE THEY BECOME THE THINGS YOU HAVE
