<human>: Could you distill the essence of the text into 1-3 sentences?

We went to different Unis that were close and through friends we met and were good friends for 2 years. In my third year (he graduated at the end of my second) we started seeing each other bit more and ended up in a relationship. As we were friends it worked really well because we already knew each other. 
We did distance for the last two academic years with this year seeing each other primarily on weekends. However with it being my 4th year I was very stressed and would often bite his head off and we grew quite distant not really connecting. I finished in May we are moving into a flat by my Uni next week with our best friend (I have my 5th and final year this year) We all get on so there is no issue having a third wheel. He can wfh or drive in so it's fine location wise. 
Our flat mate doesn't move in until September so it's just us. During holidays from Uni I tend to spend quite a bit of time at his, we happily spend time apart in the same flat and can easily entertain ourselves. 
However he is worried about if we broke up and one of would be homeless/screwed for rent, we like to think we will be okay and the plan is to move to his parents for a bit in Australia when I graduate so it's pretty serious. 
We don't have any underlying issues like cheating etc so that's all good.
Was just wondering if anyone had any advice on people living together for the first time how to make sure it works?
<bot>: Moving in with my boyfriend for the first time, had some hard distant times this year, any advice for first time couples moving in?
