Recently separated and falling in love

I recently separated from a 6 year relationship and have found myself head over heels in love with someone. My ex wants to work on things and in the beginning I thought I did as well but the connection with the man is something I've never felt before, not even with my ex. He has started asking if I am seeing someone as a heads up and I don't want to hurt him as I do care about him. But I also want to move forward with this guy, I feel as though he could be my one and only which I never thought of before. It has been very quick and unexpected as I have known him for years through a family member of his. His family supports it which is amazing and so welcoming as I was not welcome with the last one. Is it too soon? Can you really fall in love so fast?
