Can a individual love 2 person at the same time?

I think it is possible. I am divorcee and in love with a married man. He is such a gentleman who told me everything about his family life. He said he will not leave his wife and on my part I don't want anything from him except his love. Our relationship is more than 5 years old and both of us are very happy with the relationship. I also understand from other sources that his wife and children are also a happy lot. Please don't comment that he is a two timer etc, which he is not. Probably we are into a platonic relationship where the societies recognition is not a must for us. On my part I don't require anything else like a child or money from him and all we want is to see each other daily and have our own moments together.
