U already chat daily with him for 4 months. So, it is very hard for you to stop now. Him being good looking, smart, flirty and you yourself needs help with your study and is loving the attention he giving is not helping you to stop contact with him now.
Just imagine the victims in this situation. His wife and kids. You are playing with fire and u are very clear on this. You really enjoy the thrills and excitement of this game. You can continue doing what u doing now, but pls be clear of the consequence of your action to the innocent victims in this situation.
I very very pity those people who don't know their husband/wife is having affairs (emotionally or physically). They really trust their other half so much. You and him enjoying and got people suffering. Find other single guys. There are plenty of them for u to flirt with.
I know u will continue chatting with him as the bond is already strong. But i hope u know that both of u are causing misery to another woman+ kids.
