I left my husband. It was traumatic (involved moving myself and my son literally hundreds of miles to return to my home country).
ExH REFUSED at first to pay me maintenance. He was financially controlling which was one (of the many) issues of our marriage. However he quickly realised that he wanted to "move on" and "start his own family" and therefore needed my co-operation to avoid a costly divorce. I held this over him - said I wanted a legal agreement re: child maintenance or he was not getting my consent with divorce. Also insisted he paid ALL the legal fees.
I got myself a job, rented a small flat and saved like mad. Managed to get the funds together for a mortgage deposit. Luckily I was eligible for first time buyer deals as I'd never had a mortgage here.
At first I found it really difficult. I felt like people were judging me when they realised I didn't have a partner. No one actually said/did anything - it was all in my head! I also struggled processing all the crap that happened. It was sort of like the more I sorted myself out and got my head "on track" the more I was able to see how messed up my marriage was. I also struggled a bit with the emotional load of being my son's sole carer e.g. if I got sick I still had to look after him (nasty with a vomiting bug!).
The LAST thing on my mind was getting involved with a man again. Part of this was due to my own childhood - my parents divorced when I was young and my mum had various boyfriends over the years and I HATED it. I was determined I would never put my son through that.
However, fate intervened. After 4 years on my own I met the perfect man randomly in an art gallery of all places (well perfect for me - he has his faults lol!). He is genuinely my soul mate (sounds cringe typing that - I never believed in that concept before!). We've been together 7 years now and I couldn't be happier. Life is so much better.
It will be difficult at times but looking back I wish I'd done it sooner!
Best of luck with it all x
