OP didn't say anything about biological father being completely missing.
Apart from in her first post, where she states very clearly that the bio dad met his son twice as a baby, but has not seen him since. Not sure how you managed to miss that.
Also OP mentioned something about biological father wanting to have sex prior to abandonment ( allegedly) What it looks like is that OPs sons father is alive and probably not far away.
How does it look like that? Where are you getting that invention story from?
It also seems that his contact with the child could gradually be re-established. What problem OP has is that she feels a bit guilty of watching her son knowing that reasons for this bs are not really legitimate and at the same time tries find reason to justify her approach to it , hence story about abuse and sex.
Eh? You are coming across as a bit mad. Could you try this again, with logic?
OP wants to keep her new relationship uninterrupted, hoping that everything is going to be ok
OP's relationship will be just fine, whether the bio dad ever shows his face or not.
She has no need to 'hope', & can manage suitable contact - & her son's feelings - if & when it happens.
Another thing is ,OP needs to call biological father and see where he stands when it comes to seeing his son.
She already knows. He has not seen his child for 4 - 5 years.
It's not her job to chase the child-abandoner.
If he wants contact with his child then step daddy needs to back off.
Step daddy doesn't 'need' to do your, or the child-abandoner's bidding.
He will back off and still gladly do his step daddy/boyfriend chores with smile on his face. Don't u worry lol those guys have no standards they will do anything for access to some cuch . After all he went after a woman with newborn bwahahahaha
You are a very strange little man @GregAdams1
I hope you are getting the psychological intervention you need.
