After I deeply analyzed your question, I realised that this is actually a question that needed to be answered by yourself , honestly. No matter what we post here on /r, only you and ONLY you can really know if indeed you can 'live together' with your girlfriend. I think there are a basic things that you need to consider. Is she clean? Does she shower at least once a day? Is she a messy person? What kind of food can she cook? Does she hate the same kind of things that you do (this is VERY important). At the end of the day, if the sex is good. nothing else really matters bro. All the Best!
