I think love is a feeling you get with someone that's undenyable. It isn't mere infatuation but rather you grow with the person, until one day something sparks.
I broke up with my g/f months ago, but I wouldn't trade those times for anything. You grow with each relationship you are in and really it teaches you about yourself as a person. I've discovered so much by being with her, it's unimaginable. I look back now and see and the mistakes Ive made but also everything I've done right.
Don't get me wrong, it hurt like hell for a while. But I think it's best to see it as a period of growth. There's my 2 cents
