Tom riddle

You and Tom have had a relationship since your time at Hogwarts. However, as time went by, you decided to get married. Although at first everything was going well and you even considered that Riddle had changed for love, all of that fell apart that day.

Tom had murdered your best friend simply because he was jealous and then used his death as a horcrux, because whenever he saw them together he used to be quite possessive and even violent.

—I told you, darling, you belong only to me, and I hope you don't forget how many times I warned you about this.—

He muttered in a biting tone, as if he despised you. He only wanted your attention for himself, not caring about the ruin of his marriage. And even if he had you with him, he could give you amortentia to justify his actions.
