you just have to feel you deserve unconditional love and then you'll be able to find it .... you'll know. It takes time though ... patience and time. If you give up on the possibility, you build a wall between making it a reality.
I know I deserve unconditional love. I am also open to the possibility of it. But I am not and never have been one to go out and look for it. So if it happens, it happens. I was happy for 20 years being single. I am ready to find that happiness again.
