Refael,
I'm not sure if you are dating using the shidduch system, but if you are, understand that it can be hard and challenging. It will happen that you feel a particular girl is "the one" but she will reject you. You might feel that no other girls will be as good. But as David mentioned above, Hashem has a plan. G-d willing you will meet the one and you'll realize what Hashem plan was all long. Wishing you much Hazlacha.
