I have found that as I have grown older I find it very hard to make friends. I've only lived in the uk about 7 years and have made one friend who I rarely see but speak on the phone to or text every few months. Life gets in the way I suppose. I'm a lone parent too and have given up trying to find love. I have found that I now tend to isolate myself I guess as a way to guard myself from rejection, be platonic or romantic.
My only source of socialising is either on the school run when I say hi to another parent in dd class, my one colleague or the person running the till when they do make small talk. I am very lonely and dd who is 6 is really my only friend. Today was my birthday and so I said to her we could go out to lunch and while there she could go to softplay to which she declined. I felt shattered and it really struck me that I have no one else. My dd one Christmas even said mummy why didn't Santa bring you a present as I chose to spend on her than myself and didn't want to buy myself a gift and wrap it just to make believe for dd.
I just wanted to let my feelings out although you may not fully grasp all I was trying to say as I am very emotional.
