i meet her

You just say it. Saying "I love you" doesn't have to be a complicated thing. If it's really something you feel, saying it should be something that comes naturally. You shouldn't feel shy or ashamed about your feelings.

Just tell her that you like her... but then be aware of the consequences and that you ready yourself for any outcome that may result ok? Be brave and be strong. Just tell her.

You don't have to express it. She knows it very well through your eyes and the body language. Women have a sixth and extra skill to smeel and sense the men better by reading their eyes and actions. Just continue to remain in her companionship as long as it's possible to you. A day would come she may ask you what's your opinion about marriage or she would ask you what are your views regarding your wife or may be she may ask you "do you love me" Wait & watch, don't make a hurry that spoils the hormony and the secret of successful love. All the best from oarnamav.
