Looking for a serious relationship

I'm 45 years old I have been single for almost 5 years. I was born in Tehran Iran and at the age of 5 years old I moved to Germany and then to United States. I speak 4 different languages and I'm very smart and intelligent and educated. I consider myself as a gentleman and very genuine and kind hearted. I have 4 grown kids and all in college I'm looking for a serious relationship that can turn into marriage one day. I know what I want and definitely ready to settle down and live the rest of my life with my forever love . I was raised with morals and dignity and I know how to express love and affection so please never judge a book by its cover thank you
