Before you start judging me before reading this, I want to make things clear. The person in question is my ex-stepfathers niece, he is no longer my stepfather after my mother passed away almost 3 years ago. Now we never really had any prolonged periods of contact other than maybe a few hours at a time irregularly, but recently she popped up on one of my tinder sessions, of course I swiped no, and thought nothing of it. However her picture came up on my facebook feed today, and I suddenly felt a wave of attraction towards her, I know there is nothing technically wrong with this as we no longer have anything to do with each other, but still I don't know what to do about this.
