IMO I feel Jake is out of line and his question about "who's **** were you sucking" is completely wrong and inappropriate. He has no business asking where you are or who you're with or ripping the blanket off you and taking pictures. Do your best to avoid him and since your mother agree he's giving off a creepy vibe.....tell her not to let him in the house anymore. I think you should tell your parents what he said to you. He's bad news and rude. Always trust your instincts. He has no reason to act like a suspicious BF and no business telling your parents to switch phone companies. Your dad's his boss and Jake needs to remember his place.
