am i doing the right thing?

me and my boyfriend have been having serious talks about our future together. we've been saving up and got our priorties straight. we are great with each other very loving comfortable and intimate with each other. lately the topic of our conversation is moving in together. our fmailies are very supportive of us and my family takes him as there own and likewise with his. my boyfriend still lives at home obviously and i'm there everyday morning to night. my mom has been giving me doubt about the idea and she doesn't agreee with it at all. emotionally and physically i want to move in with him. he's my first love and first everything (i've had boyfriends before but i've never did anything with them or love them) i'm compelety head over heels. i just don't want us moving in together to ruin our relationship and we then have issues. are we moving too fast ??
