I was wondering if anyone else is or was in a similar position to me and could help me work out how I feel as I just don't know.
My (now ex) husband had an affair 8 years ago and we split up . Horrific at the time (but it's how I discovered mumsnet and will be ever thankful for the support I found on here).
Fast forward 8 years and we have 7 and 10 year old DCs All is good between us and he has turned out to be a great Dad.
After a couple of years I met someone that I had known when we were teenagers. I wasn't looking for a relationship at the time but we were both completely blown away by how it happened. We fell 'in love' ridiculously quickly and started planning our lives together pretty much from the 4th date ( I know.. of course looking back I can see how ridiculous this sounds but it felt so right and the connection between us in every sense was like nothing either of us had experienced before) he met the DCs after a year and he became a part of their lives for 3 years.
It didn't work out, turns out we were incredibly different, the distance and also in the end he struggled with the idea of the huge change that comes with having DCs in your life , there was no lack of love there but we couldn't make it work which took me way longer than the end of my marriage to get over as they feeling ran so deep.
I have had 2 years on my own. I tried on line dating and whilst it didn't result in anything long term, and I found it quite brutal at times I am accepting that at 44 it's probably going to be the main way to meet someone if I decide to get back out there. .
But do I want to? I know society says I should and sometimes I can think of nothing I would love more than to have that closeness again, a partner in crime/ life. Someone to snuggle up to at the end of the day, share the load with etc but I can't work out if I want to. I have some friends who genuinely happy relationships / marriages but for every 1 there seems to be 2 or 3 that don't .
I do get lonely but have a good network of friends living nearby. The DCs are happy, I don't have loads of money but life is quite simple and happy. It feels like we are a good team.
But I don't want to grow old alone and I do miss the closeness of a relationship and loving someone/ being loved . I can't work out if I am just scared of getting hurt in such an awful way again and maybe it's just a defence mechanism, or whether I am genuinely happy on my own! I tell myself that relationships are too much hassle but I wonder if it may not be quite that simple and I am just trying to protect myself.
I have had counselling quite a bit in the past and that had made me much more self aware so I am in touch with how I feel. It's not an option financially at the moment.
I know this seems like a small issue and maybe I just need to sit with it, not worry about it but I'm just confused. Of course I would probably say to some one else ' don't go looking for for it, if it happens it happens' but I'm not sure it would 'just happen' without me doing something about it.. do I want to? It feels like throwing myself back into the lions den and risking getting hurt again ( I know I should see it as something positive) .. I think I have forgotten all the good thing that a relationship can bring so I just tell myself I don't wan't one! 
Sorry for the long post! Any thoughts gratefully received.
