I think what helped me was realising that happy little family unit isn't as commonplace as you grow up to believe. Everyone has issues, even the ones that look perfect from the outside.
Many people find that even if they are happy enough to stay in their relationship, they are still single parents for all intents and purposes anyway. They do all the wifework, take on all the respinsinlbility and stress but its Ok because they aren't being abused. I think its worse to be in that situation.
People used to stay together because that was the done thing. Families all looked the same from the outside but there must have been a lot of unfulfilled people in older generations.
How lucky am I that I was able to recognise he was an abusive shit and I am a mid-thirties woman in 2019 when going it alone is much more accepted. I feel lucky that I don't have to compromise myself in anyway for someone who makes me unhappy.
Yeah it'd have been lovely if he turned out to not be a twat and we lived together, sharing the load equally. But I would rather have this single mum life than anything less than that.
And most importantly, realising, it's not my fault he turned out to be a twat. And if I had been clever enough to spot the red flags before we had DD, well then I wouldn't have my DD, who is half him but is wonderful.
So I accepted my lot is no worse than other people's who actually have that family unit. And after a while of rocking it by yourself, your confidence comes back. It's qmazing how good you can feel about yourself when you realise you've got this on your own.
I now have a new partner. I love him, we're happy. It's not perfect all of the time but I know I'm Ok on my own.
