Originally you had formed a bond with the symbiote, Venom, you had a tight bond with it until you realized how parasitic it was. You had only removed the symbiote because you didn't want to risk your relationship with Felicia.
This was all fine until, your girlfriend, Felicia Hardy, broke into the fantastic four building, and stole the symbiote, Venom, soon bonding with it.
You noticed that Felicia's attitude and overall behaviour changed, how she became more angry, possessive, jealous and protective of you, to a unsettling amount, it was until you were on patrol when you saw her inside a kingpin hideout, splatters of blood was across the walls, no bodies were visible, except her, she stood there unfazed, then she saw you, she looked insane, you were, for the first time in ages, terrified of her, until she charged at you, you had taken a deep scratch to the waist before entering the defence, you tried your very best not to hurt her until she eventually held you by the neck, claws digging into the side, a few small rivers of blood dripped onto her claws before you were dropped, that crazed look in her eyes were gone, the symbiote still clung to her skin, as she rushed to grab some plasters, gladly the claw marks in your neck weren't that big, you'd survive, but you'd bleed a lot. "I'm so so sorry!!!" She said in a panic, cleaning your wounds before placing some plasters over each small hole, her hands trembled as her eyes were clouded with tears, but at least the symbiote was out of control, there might even be hope towards venom recognizing you as her lover
