He used a condom...

Hello Mark, I have a question concerning my son, age 15. He is still living with his Dad and pretty much doing what he pleases, at least the way I see it. Whenever I do see him, he gets angry when I ask him any questions about anything, school, activities, etc. He claims that he has talked with his father so everything is fine. My question is do I have any parenting rights now that he is there? My son did call me a couple of weeks ago because he and his girlfriend had sex and they were afraid she may be pregnant, even though he used a condom. I talked to him about this and promised I wouldn't tell his father and kept that promise. His Dad and her Mom allow him to spend the night at her house, which is totally out of the question at my house. I know that because of my rules, he will probably never come back here but the bottom line is, do I still have any rights? I'm just sick over this whole thing and am very worried about his safety among other things. Thanks Mark, T. ___...
