When you are "running" through life, busy, busy, busy, social, driven... There is so much noise in your head, you have no way of allowing intimacy anywhere near you. You can't feel anyone else, because signals can't get in. There's just too much internal traffic to connect with anyone on the outside.
I think it's important to slow down, quiet down, find a headspace that allows some sort of meditation. Then, you can start thinking and being open for intimacy to happen.
Don't know if I was running from intimacy all those years or if I was making myself crazy to avoid it or to avoid the pain of not having it in my life. Either way, I'm done running.
