I can't stop thinking about my mom's boyfriend's son, and I like him so much - but I don't know if he likes me! We share a room every other weekend when I go with my mom to stay. Help somebody!! What do I do?

If your mom and her boyfriend are serious at all then you should probably not go after her boyfriends son. I guess it just depends on if they're cool with it. Just make sure to be yourself and flirt and if he likes you it should work.
