Think long and hard about the kind of relationship you might want to have. After a string of unsuccessful relationships in my 20s and marrying the completely wrong person in my early 30s I had a good, long look at myself and why I was ending up with men completely unsuitable to me.
By the time I'd left my ex in my early 40s, 2 young kids in tow, I had a much clearer idea of what kind of relationship might make me happy.
It was someone who I could enjoy spending time alone with, who really cared for me, who I could trust and be open with. I was no longer interested in how that person was in social situations or how others might perceive them.
And I didn't want to be with someone who was difficult, grumpy, distant, provocative, drunk too much regularly, something I had experienced so much in the past. I found that I had chosen men who were either destructive or unable to engage, or both. And those choices were about my own insecurities.
I know a lot of luck was involved, but at 42 I met the love of my life and recognised it immediately. I am an atheist, but if I wasn't, I could almost have described it as someone up there finally looking out for me and helping me find happiness. 11 years later we are still happy and now married.
There is hope for you. But you might want to look in depth at why you have ended up and then stayed with these unsuitable men.
