Archie, My brother and I were adopted and then my parents got divorced when I was 3 and my brother was5. He was rich and tried to buy our love with all sorts of things. Including cruises, aspen skiing vacations, disney world vacations, any new gaming system that came out and a back yard that had a basketball court, jungle gym, jacuzzi and hiking trails. She was a single mom with two boys. She could simply not provide those things. However she truly loved us and was there for us. She listened to and cared about what we thought and had to say.
I have not seen or talked to my dad since I was 16. I was always close to my mother.
I am actually raising my oldest daughter even though she is not mine and I am not with her mother anymore. Her biological dad is still alive and they live in the same town. I live 40 minutes away in another town. She comes over to my house all the time. She has to be forced to go see her biological dad even for an afternoon. It is hard watching him make all the mistakes that my father made.
You cannot buy a childs love. Simply won't work. When your son is grown he will know who loved him and was there for him. Same as my daugther will. In the end you will win simply by caring and spending time with him. It is tough, man do I know that, but the goal is worth it.
