I don't think she is tooo attached, but anyways I want to say something like.."I want to be able to give myself fully. I was able to do that about a year ago. But now I can't. I just want to be able to get there and I need some time alone."
A year ago is when I met the ex. And it felt so natural and I was happy to give everything I had. With the friend I am not feeling that way. The friend should know that when I am with someone its not just for sex. Although I will miss that. That message will probably get back to the ex too.
