<human>: I've been living with this guy 'Leo' for about a year and a half now, and we've always found each other attractive. Towards the end of last year my relationship with my ex was growing rockier and rockier, and we eventually broke up earlier this year. Shortly after that, Leo and I started a FWB type relationship. As we are now moving into a new apartment with 2 new housemates, we have decided to end it, however I am a bit concerned about how this is going to play out. 

Firstly, the sexual tension between us has not gone away, and even after Leo said we should stop (which I agreed with) he approached me again for sex just 2 days later. Secondly, I've always been relatively confused about what my feelings for Leo actually are, and I'm worried that I'm actually beginning to like him more than just a friend (which is why I'm doubly pleased we are ending our FWB thing), although if that is the case, it's definitely not too serious, just maybe a crush. So - how can I best move forward from this non-relationship? I can't exactly actively avoid Leo, and obviously we are going to need to establish rock hard boundaries in order not to make our new housemates feel uncomfortable. Has anyone been in a similar situation before that can give input as to the best way to move forward?

Can you summarize the given text in a few sentences?
