Long story short neatly 15 years ago right after I turned 21 I got drunk at a family gathering at my inlaws house and of course acted stupid. To this day they still hold this against me. From time to time they demand another apology, they insult or make fun of me. They never take anything I say seriously ever. If I try to have any conversation at all they usually either ignore me, scuff at me or tell me that what I have to say is not important. They label me as a drunkard and say that I'm an alcoholic although I hardly drink like I use to when I was young and in college. One of the family members even works in a drug rehab center (the person is not a doctor). At family gatherings since then, everytime they offer me booze and they feel the need to tell me where the alcohol is located and everytime I'm always telling them no I don't want anything. They are always hanging this over me.
What I don't understand is why do they do this? When they did stuff like cheat on their spouses, get arrested or had drunk driving related incidents NO ONE is allowed to bring it up or discuss it yet it's perfectly fine to discuss my shortcomings from nearly a decade ago.
I have gone through alot in my life from almost being killed by a family member trying to set me on fire, to being raped. I forgave those who hurt me to help me heal. So I don't understand why my inlaws can't forgive me for my bad actions so long ago and I get treated this way.
Is there a name for the behavior that they are displaying? How should I handle this?
