I thought about pouring a mug of boiling water on my neck to hide my affair.
Oh my gosh, that would hurt you badly. Why, just why, would you harm yourself with boiling water?
I feel like it would be deserving to me but hide the hickies she left there on my neck too.
If you have to go to those measures to hide something from your girlfriend, you know you've done wrong. A better solution to that would be to just confess or move on from the old relationship. Your precious neck needs to be in one piece, not burned.
Its both our faults, we had issues of our own in this relationship. I think this is the only way out.
Oh I see, is this how you feel? Ending a relationship is much easier for most. You should not feel the need to hurt yourself and someone else over this incident.
