I don't know what to do end it or not .
My gran has a sister ,her son has a son who has a step son ..it's not he's real son he married he's mother when he was 7 years old but calls him dad .
We met on a night out ,never met in our lives as that side of the family are not close .
Starting seeing each other not realising ..we aren't related ..but still are if that makes sense .
We really like each other but not sure what I want to do ..so it's my grans sisters, son who has a son who has a step son ..
Wrong ? Ok ? Advice
