Ursula I agree. Nobody can change themselves for anybody. We can just find someone who loves us instead. 
On a different note. I have now sent a message to all the 5 people that I thought I could date in OD. That's it. All done. Not sure if I am meant to be single at this rate....
I have been also reading a lot of self help kind of videos too.
Like this one.
I knew about the "finding yourself" thing in my 20s, and doing things which you love will turn you into the person that you want to be. That is why dancing is also important to me too. But I came to also realise that, I have given too much in the pursuit of my own hobbies instead of giving as much in the intimacies in building relationships with others too. I find this area quite confusing really.
I did message a little bit with this guy that I mentioned before that I have known him in my 20s. It was really pleasant, and he was kind with his comments too. Maybe I judged him too harshly before. We haven't really messaged one another after, and I do not know what to say to him at all...
On another note, I have been going out with this girlfriend and having a laugh about our foibles. It does feel less lonely doing this alongside someone else too. We both came to our realisation that we had been picky, a little bit. Although it isn't our set out intention to be picky, since we have not been picking, but we did eliminate someone very quickly without going for very deep meaningful relationship first. I really think that we are both quite scared to be honest...
