freetosmile.....there is no way that you are obligated to this guy. NO way at all!
When a person voluntarily gives or does something for another.....it is a gift. A gift does not require anything back.
If, however, the thing or service is given with the expectation of something back, in return, it is a manipulation (not gift).
I"ll give you the example of a man that I knew very well--we worked together for several y ears. He was divorced and had 3 children. He an his ex shared custody.....
This guy was crazy about his kids....couldn't do enough for them and the ex....
He later, remarried as did his children's mother.
I never, once, heard his say that the children's mother "owed" him a thing. He never seemed to resent what he gave or saw it as any kind of leverage. He just wanted his kids to know that he loved them.....
Just remember that you do not owe this man anything.
