I am 20 single but I am inlove with a 35 year old man now, before I was inlove with a 45 yr old man. I don't know, it just happen that my heart beats fast and I always caught myself smiling alone like insane whenever I think of him or see him. I dont see anything wrong unless the man is married and have an affair to a single woman like me. I'm inlove but still in control cause I don't like relationships.
