Hi... I suggest not to look at it from a moral point of view rather from a practical perspective.
Yes, it is possible to fall in love even while being married to someone else and feel obligated to sustain both relationships. But again it depends on the person involved.
You can't guess what's in their mind and how they really feel about you. You have to make your choice based on what you really want and to what extent you are able to compromise on your expectations.
So the important question here is whether you are okay being in love with a married man and what future do you see with him?
