i didnt speak to my dad for about 4 years due to him lying and breaking up family,
i then thought what would i do if something happened to him?
i started speaking to him and still do dont get me wrong its not a good relaionship he has his new family and he's a different person to who i knew but glad in a way i speak to him..
if your not going to every talk to him again i would maybe send cards back and a letter telling him how you feel, by keeping the money you are probaly giving him hope that you will speak to him again,
