Difficult situation with this girl, how do I avoid getting friend zoned?

thats pretty difficult.... seemed like everything was going well till getting back with the ex. askn to stay at a place is a pretty big thing.... but there might be somthing that u might not want to involve urself in also (if ur that type of guy) you guys seem pretty close and something is gonna be decided at this weekend.... so just cross ur fingers and buy a pack of durexXD
