You don’t deserve to get married if you cheat on your soon-to-be-wife at your bachelor party because it’s your “last night as a single man,” motherfucker please. You haven’t been single since the day you asked for her heart and for you to throw it out for a “final night of freedom” as an excuse just makes you an undeserving disgraceful bastard. I hope she leaves you and you end up spending the rest of your life alone.
I’ve been cheated on before and as soon as someone cheats on me, all of my feelings for them go out the window because I know what I’m worth and I’m worth being a priority, not an option. As soon as they taint my trust, there’s no way of earning it back and they will never call me theirs again.
I’m sorry I can’t really give you advice but I have never had a problem with walking away from someone or getting over them if they wronged me.
