German woman cheats on her husband with a neighbor

In my marriage, I have always been the one who has carried the emotional weight, household chores, etc. Recently, my husband falsely accused me of cheating on him and said he was going to leave me, so I decided to teach him a lesson. Since no matter how much I tell him it’s not true and there’s nothing more to do, I’m going to give a blow job to a friend I’ve desired for a long time but haven’t done so because I was an idiot.
