There's no right or wrong answer to this question: how do you know he's the one? I used to wonder about that too and the more I thought about it, the more I realised, I wouldn't understand until I felt it.
It's completely normal to have that question lingering in your mind. We don't want to waste our time, feelings, and energy with the wrong person. Some people want to bring the relationships to the legally binding, and some want both parties to reach the same level of commitment. One thing that we all share in common is to have a good relationship with a good person. A relationship is each other's commitment.
It can be so easy to say 'I love him!' at the beginning of the relationship. We are filled with the excitement, the joy and perhaps certain expectations. Sometimes, we are also blinded by the idea of love. People cross each other's paths for reasons. And naturally, we hope the reason is a wonderful one.
If there have to be signs that you have found the one, these are probably what I can tell you, purely based on my understanding and experience. Please note, that I am not an expert in relationships or love, these are purely my opinions.
