Yes I have, well, I was in my 20s but I still refer to it as my mid life crisis.
My relationship was rubbish, we’d been together 7 years and I felt like I was carrying him, he didn’t work and I worked 2 jobs 7 days a week, struggling to get by, had a house but regularly went in arrears with the mortgage, lived away from family, lost touch with all of my friends, my main job wasn’t working out and I really wasn’t enjoying it and I remember asking myself “is this it for the rest of my life?”
It was about a week after my birthday and I told him to leave, I went through some shit times in the immediate aftermath, had to move back home, changed job but with a serious pay cut, lots of changes!
8 years on and life couldn’t be better! Married to the man of my dreams, a beautiful DD, a career I love and I don’t regret anything, not even the hard times, not the times with my ex, because I wouldn’t be who I am today or where I am and I wouldn’t have what I have and appreciate life the way I do if I hadn’t have gone through it.
I know this is very different to having been in a relationship for decades with children, but sometimes you’ve got to take the risk to get what you want, that doesn’t necessarily mean leave your DH, but find the route cause of your unhappiness and fix it as best you can, whatever it takes.
