I think this N is good for fun. I know one guy like N who dated my LG's best friend (Over 30 y friendship, she is a successful lawyer) for 3 more years.
He is very good for fun, work around house, very close to her young son. Even son wanted Mom to marry him.
He did ask her for marrige for several times. She just not wants.
Finally, she dumped him two years ago.
