Relationship with some one younger

I'm 61 years old and met a guy of 34. He is lovely, charming and an interesting person. But I'm wondering if such difference of age shall be too much. In my opinion younger people at the end always leaves you. I don't know if this thought comes because of my former relationship which was not a nice one. Would like to revenge your comments with interest I had 3 relationships always with younger boys, mostly 15 years younger than. Myself. And after 5 years they finished.
