Advice? Living together?

So me & the bf been arguing a lot before bed & we live with his parents not just alone so we are couped up & I feel like I lost myself in our relationship I gave up living with my parents & doing what I usually do & now Im in his room watching him play a game or do whatever ge wants & I love him forsure but how do you make living together work? Ive been considering moving out because of the fighting & I feel it would be better for the relationship & wait to live together until were married, my aunt told me if we live together before marriage im not motivating him to get the 💍and I agree with that because im playing wifey but theres no ring on my finger weve been together a year & a 1/2 & up until moving in weve had a great relationship and were happy but as of late things changed within 4 months so far & Im scared were going to break up because of the fighting and if its going to get worse! Please give me advice how should I go about this? How can I improve our relationship? & have healthy co habiting?
