Hi and thanks for your question. You said the key. You never seem to attract it. When it comes to unconditional love you want to be the person that creates it. When you create something from within yourself and share that feeling, then and only then can it come back to you.
You want to be the one to give the exact thing you want, in this case the unconditional love. When you yourself can start to do that then, you will attract it.
In saying that how do you do it? You do that by not putting conditions on your love for the person. That would mean that it is okay if you have a relationship and they come into it with conditional love.
How does that help you? When you are not expecting something of another person and you are accepting them the way they are then you have brought into the relationship the exact thing you want and now it has a place to start from.
I found out in my life that when I changed the way I acted toward a person they seemed to change. But I soon realized it wasn't them who had changed at all it was me. Not only did I no longer have an expectation of them, by treating them the way I wanted to be treated created an entirely new experience with that person.
I discovered that with my mother when I said to my sister, mom has really changed. She said, "I haven't noticed anything." That is when I knew it was me who changed my attitude toward my mother from one of expectation to one of love and admiration for her.
Funny in doing that I ended up with what I had been hoping for from her for years. She started to give me love back and admire me.
Try it out Sally; you will be surprised how it great it works.
Wishing you all the love and happiness the Universe has to offer! Dawn
