What do I do with my situation

I'm just your average 23yr old male living in Melbourne which happens to be bi-sexual but to everyone else who assumes and thinks they know me better gay.I grew up in NSW with my older brother and younger sister until I turned 17yrs old, that was the day my life turned upside down.On my 17th birthday I told my family I was into other guys, they were pretty cool with it not one negative thing about it well so I thought.A week later after my birthday I started sleeping around as I was told it's good to have sex and relationships are just crap so I listened to people's stories and went with it.I had a lot of unprotected sex you can say I was stupid and yes I admit that I was but I had a good doctor who gave me a blood test every month for the normal STI/HIV test. They always came back negative which was good.For nearly a year I was just going around the block and sleeping with this guy and that guy until I wanted to try have a relationship..........skip a head the guy was a dick like the the rest after him and before now.*********FAST FORWARDING*********2014 I moved to Melbourne to permanently live here instead of NSW I had two relationships with a female and one male between the last two relationships I had another test as it was while since my last test good results they came back negative.My last relationship I had was for 1.5 years and sexless and me unhappy for all of it beside the first 4 months. I had my suspicions that my partner was sleeping around behind my back like most of them have in the past but anyway he said he wasn't so i believed him.After that relationship as we decided not to continue on as there was one to many arguments and nothing working out (the truth his brother was a prick and thinking he can tell me what to do in my own house as he got kicked out of his girlfriends house for being a dick).I moved out to a place with friends which is like a share house. This is where things get more hard for me.One of my housemates is someone I liked, we spent a lot of time together watching tv and movies, going out and doing things.Between us we grew feelings for each other over time I started to fall In love with him he knows I love him and he loves me but we ain't in a relationship.I'm aware that he wants one with me and I want one with him but we don't want to rush it, during the time of a month or so of spending time and feeling more for each other it's gotten to the point that we would leave each other's side.We share something special that no one will understand but that's not the point to this, I was given some bad news by my doctor a few weeks ago and it's taken a turn in my life.I got a phone call from my gp (doctor) to come in and speak about some results, when I got there I knew it wasn't good news but hoped it was good. My doctor told me my blood test came back as HIV positive.I told everyone I live with and I believe the guy I love took it worst then I did. He says he ain't going to do anything but wanted me to do another blood test so I did and it got confirmed that I do have it.As it's been confirmed the guy I love is not sure what to do exactly but wait for me to see more medical professionals at the clinic who specialises in this.HoweverI feel like he is becoming more distant and pulling away but scared to say it he has said that he doesn't want to leave me but he would feel bad if he does as there would be no one else that would care or support me so he stays.I feel like he is forcing himself to stay so I don't get hurt and feel like it's a waste of time of what we have etc.What should I do??? I don't know what to doEvery night I become emotional I cry a lot even though I sleep next to the one I love I try not let him know that I'm crying.I think he is going to leave me eventually at some point soon but not sure. He talks to a lot of other guys and I don't like it but I can't say anything.I'm more jealous of some people he talks toAll together I can't pretend that it doesn't bother me but then I can't push him away all I will loose him for good.What do I do
