<human>: Condense the text into a few key points

Please don't make fun of me for still living with my mom, it's part of my culture to live at home until we are married. 

My boyfriend and I have been together for 3 years and love each other very much. We are almost perfect for one another. He has lived here with my mother and I for 2 years while I've finished undergrad school and now I'm almost finished with my Master's degree....the agreement was that we'd move out on our own once I'd finished my Master's and so here we are. We have all of the big, expensive items purchased and stored in my mom's garage (such as furniture, washer/dryer, fridge etc.), it seems like we are good to go. We even have a comfortable savings account just in case. We locked in a lease in an apartment and are moving in in December, woohoo! It's just... I am terrified! I've never lived on my own before, it has always been me, my sister and my mom. I'm scared or leaving her behind, I guess. I'm so used to seeing them everyday that it will be weird not seeing them that often anymore. What if my boyfriend and I don't get along? What if bills become too much? What if we fight a lot and eventually break up?? 

I know I'm freaking myself out and thinking too hard about this, the rational side of me knows it's time to move and spread my wings. Time to be an adult! I'm wondering if anyone here has ever experienced this? Have you ever been scared of moving out? How did it go?
<bot>: moving out with my boyfriend in 2 months, I'm extremely scared because I've never been on my own. Could use some advice regarding living alone with a partner...
