My boyfriend and his mother, What the hell?! (long but please read properly)?

first off, you need to know if his mother acted like this with his previous girlfriends. It could be that she is over-protective of her son or she may just not like you. Idk, because even if he is cheating with his mom ( which is hella weird ) why not just say "I'm going to see my mom" . Like that's the one relationship that you would never suspect so why not just tell the truth. He smells like her under his clothes thats just too strange. Seems a little to close to comfort for me. Only way you're ever going to know is if you ask him. But if I were you I'd head for the nearest exit.
