We've been dating for 8 months and we spend every possible moment together. I go to his house after long days of school and pretty much have spent every weekend with him since July 2015. He just asked me to move in!! I don't know what to do. I've asked a ton of family, including my dad and they all keep telling me to do it. But this is a huge deal... He also lives with his mom and his brother. We have already discussed this with his mom and she's perfectly okay with it. 

What do you think?! I really need help!
