<human>: My bf and I have been dating 9 months, and we've known each other for 5 years. It's been a supportive, committed relationship, but there's been no mention of 'I love you' yet. Due to financial reasons, we decided we're going to rent a two bedroom apartment together, but he recently brought up some concerns that (since he's in a high-stress job and we're on different schedules) we'll start to fight a lot more or we'll find we don't have enough space. We bicker, yes, but it's usually lighthearted, and I can only think of about two or three times that we've fought. After an argument, we always talk it over, and rarely stay upset for more than a day or two. Altogether, I know there aren't a lot of signs that we'll end up at each other's throat, but I'm worried about whether or not moving in together is a good choice. I'd also like to hear some advice and tips on how to keep everything going well, hopefully it can put both of us at ease.

Can you summarize the given text in a few sentences?
<bot>: Moving in together after 9 months, just worried something will explode and go horribly wrong, and need advice to feel better about it.
