Sometimes the right person reappears at the wrongest hour.
Sometimes your in a great relationship, and then someone new reappears and takes your breath away.
Sometimes you feel like your not worthy of one and then you click with someone from one day to the next and you find out your completely ready.
It depends on a bunch of things.
However, I do feel its important to feel confident before entering a new relationship because if your feeling lonely, empty, insecure… then the chances of meeting the right guy or building the relationship on a healthy basis will be unlikely.
