Hey a resentment!
It onlys hurts you, he probabaly doesn't know or doesn't care.
Identify the feelings it hurts in you, anger for him taking advantage of your dad, and by extension, you.Take some time ,maybe write it down, sit on it for a day or two. Then reread and edit until you get clear what you want to say, and how you want to say it.
You have some feellings toward pops too, address those at the same time.
Not in anger, but in honesty.
Say your peace, then let it go and be free of it. Good luck!
