In the beginning after useless ex left (for his affair OW) I was in a lonely place. I needed to fill that hole.
Long story short, I had four sexual partners in about 18 months, each lasting around 4-5 months. But I was trying to replace the hole in my life and thankfully had the sense to see these men weren't right and I was being weak to try to make them fit my life. I ended it with three, one ended with me. At that point I was very low.
I forced myself to do things as a lone parent so booked and went on holiday, theme parks, travelled abroad alone when children were with ex. I changed my perspective. I instantly became happier. I accepted being a lone parent.
Now I'm not bothered if I'm on my own. I've on line dated and have got fed up with that, I can weed out nice men but they mostly want sex. Again, sometimes I choose that but over time I've not needed it.
It's been three years until I feel this way just for time comparison on how you feel now.
And the only other thing I need to tell you..... But it may sound really odd!
Loneliness goes hand in hand with my menstrual cycle. I've now plotted it because it's so consistent! It's after ovulation and it lasts about 3 days. Then it goes and I swear I never feel lonely the rest of the time at all.
