All I can say is if our honest forgetfulness, a frailty on the part of man, is looked on as a deliberate act against God, then we all need to live in the confessional 24 hours a day because our whole life in this case and particular way is an affront to God.
I get the feeling that you really really really don’t understand sin… Not every sin sends you to hell for starters, as outlined what you described in a previous posting as your belief and apparently continue to believe is in fact applicable to the severity of sin.
Intent, full knowlege and willfull act is what makes sin mortal (assuming it is grave matter to begin with). This kind of sin will seperate you from God and send you to hell.
But as James says, we know that there is sin that is Mortal but also that there is sin which is
not mortal. Telling a white lie is a sin, it is always a sin. But it is not a mortal sin, you will not go to hell for telling a lie which harms no one. In this case, what the OP has done (which I my self have also done many times)
is a sin. It is objectivly a sin and no amount of ignorance can change that.
The question is, is this sin that will send someone to hell. The answer is
no, the OP will not go to hell over this. It is still good practice to confess the sin, this informs our contience and makes us better Christians. It also helps mitigate how long we might (or might not) spend in purgatory.
Because you obviously need so much help with the matter of sin, I will refer you to the CCC. You also have my most emphatic exortation to schedule an appointment with your priest or spiritual advisor so you can discuss this matter in detail:
