Moving in with your SO😬

Me & my bf argue a lot & have been on & off since Oct 2014. Currently hes been seeking anger management bcuz its ridiculous he doesnt understand it. So far it has been helping a lot &he seems to really want this to work & i do too but i had given up & he suggested that i go with him to therapy & not for anger but for relationships because they do that too where he goes. So i agreed to it. He also has been suggesting we live together & split rent which sounds cool because ive been looking for a place to live with my sibling but he said i should just live with him. The problem is this will be my first time living with a boyfriend😟 i didnt think i would be this scared to when it finally was going to happen but idk its a lot. By the way im 27 hes 28. Hes done this before once but i havent. Ever. My question, or more so im looking for advice on what to expect when living with ur SO??? Im pretty domestic, i love to clean & cater to him but i dont want to be annoying & in his face all the time & vice versa. I love being with him but we do need space from time to time & sometimes i can be a homebody. Not always but hes taking me from the city so i think i will be MORE of a homebody😬 Im just so scared this could either be a great thing n make us closer OR it could tear us apart.. He loves a woman to cater to him like cook n clean constantly n i have no problem with that at all. Im naturally just very domestic. Just what to expect living with ur SO?? Whats it like?? How to not be annoying etc. also i want to add its different for me too bcuz i live in the city & he wants to move to a suburb which im really not use to! Help😅 advice thought encouragements w.e is always needed & appreciated !
