Really??? So basically all parenting ends at age 18? Having a baby out of wedlock with a girl whose biggest ambition is working a minimum wage job is a decision that he will have to deal with for the rest of his life.
Not all parenting, but a good portion of it does, yes. Remember when you were a kid and your mom would say well you can do that when you move out and start paying your own bills? I think everyones mom said that to them at one point of another. Well, your step son DID move out and IS paying his own bills, and apparently 3 other peoples as well.
Your job now is to give advice, and be an ear to talk to but otherwise just step back and stay out of it.
News flash. Most people are sexually active at 21. Christian or no. Most people are active when they are younger than that, actually. These are two grown adults in a consensual relationship and there is nothing you can do if your son doesnt follow your own devout religious guidelines.
(And considering that his own father wasnt following these guidelines either 22 years ago, you cant really say hes doing anything that unusual for a grown man to be doing. You talk about your husbands ex doing this to him
well he was apparently more than willing to have sex with the woman and impregnate her so it takes two to tango).
As for the drinking
why should she even have to sneak liquor at a holiday meal? She is presumably 21 years old and legal to drink. Unless she is a recovering alcoholic, I see nothing odd with a 21 year old woman drinking. Should she have gotten drunk? No. But maybe she was binge drinking because she felt she had to hide it?
She is not having a baby out of wedlock yet. Lots of young women talk about babies. Doesnt mean they all run out and have them. Dont assume she is not on BC. Dont assume your son isnt using BC. Dont assume your son doesnt want a baby too. You really dont know. You dont know what goes on behind their bedroom door.
Honestly, the only thing you mentioned that seems completely innapropriate to me is the porn (only because they are watching it on a shared area tv in your home) and the neck licking at the table. Id be pretty grossed out if anyone was doing that in front of me. I probably would have pointed it out to them and tried to embarrass them so theyd realize how foolish they looked doing that at dinner.
Your son is grown man. He is supporting this woman and her mom and sister which, really, shows a great deal of integrity and responsibily. Youve clearly instilled in him a great sense of duty to family. He is taking care of someone he cares for and her family. Seems like a noble thing to me.
Youve given your advice to him. All you can do now is just back off.
