Friends with benefits who is also an ex that I'm still madly in love with!! Help please!

Me and my ex dated for a year, then broke up. It's been 7 months and I miss him, I've been trying to get back with him and he was thinking about it but he's says he's really busy for a relationship. He asked to be friends with benefits and he's giving me time to think about it. I want to try it but I don't know how It's gonna go cuz of the feelings I have! He's also suggested that maybe things could go into a relationship later on... But how would I explain to my parents that I want to go to my exs house considering I don't really go out? Any advice would help!
