My bretheren in age and gender are cursed it seems.
Just thinking about this is turning me into my parents…Suddenly much of what they do makes sense…Ok, it made sense before. But I’ll do my best to relate some of what they do to you.
First of all, if your son is slipping away because of his girlfriend, you may need to talk to him about it. Smack some sense into him…whether you take this literally or metaphorically is up to you.
My parents want to be actively involved in what I do romantically. I don’t have a girlfriend yet, but they are spending more time with the family of the girl I like in an attempt to get to know her better. If you already know that the girl your son is involved with is bad for him, you should talk to him. And be blunt.
That kind of relationship is going to have problems, and you need to come up with enough examples and sources to convince him.
If he is still not listening, you should remind him of “Thou shalt honor thy father and mother” as well as all of the moral obligations he has.
Perhaps you should also remind him of temporal matters as well. If he’s living with you during the summer, he shouldn’t be dishonoring and disrespecting the people who put that roof over his head.
I can’t say what kind of person your son is from the information given, but teenage boys generally don’t like to be pushed like that. So reminding him of all these things should be done in a way you know he won’t react to in a negative fashion.
You shouldn’t have to run away from this though. Prayer helps. But you should be praying for a change in your son, if you aren’t already.
I’m afraid I can’t offer much more in terms of advice. I myself haven’t been in a relationship like that, and I don’t know your son’s personality.
