Boundaries with roommates.

My girlfriend and I have pretty much had it to high hell with our roommate, yet our boyfriend thinks his behavior is fine. I'm just going to lay out the issues I have with him and you guys can offer any advice or tell me if I'm wrong for feeling some type of way.

1. My partners paid for him to fly out to where we are currently living. We have paid for everything he needs since frickin January. He lived with us in our old house for a few months before we moved states. We've done a lot for him, he hasn't paid rent, doesn't have a job, and yet he complains about having to do dishes and clean the kitchen. Its rather annoying because cleaning a kitchen doesn't amount to all we've done for him. And just to be clear its not like we treat him like he's Cinderella or treat him badly because of this.

2. He eats/drinks things that are off limits. For example, I told him not to touch my soy milk. That is exclusively for me since its the only milk I can really drink. I also bought two gallons of regular milk for the rest of the house to use. This boy used both gallons and a half gallon carton of my soy milk in two weeks. Its not like we say everything is off limits. Just certain things.

3. He makes comments about my weight, my clothes, my hair, my pregnancy, what I eat, etc. I'm currently 30 weeks pregnant. I feel huge. Coming from having an eating disorder, its hard enough dealing with the weight gain without stupid ass comments from him. He comments when he thinks my clothes don't fit. For example, I was wearing a size large shirt (which does fit), but the fabric stuck together at the ends and had some of my skin exposed. I didn't think to pull it down because it wasn't a big deal and I was in my room anyway so who cares. Well, he comes in to complain about having to do the dishes and then he looks at me and says that my shirt doesn't fit anymore. Even my medium shirts still fit so for him to say that my large shirt doesn't fit just because he saw my skin was completely uncalled for. He's also had what I consider an unhealthy obsession with what I eat. He thinks that I should basically eat like a rabbit and that's not happening. Either way, its not his baby so its not his business.

4. He screams while playing his video games. Even if its at 4am. He doesn't care.

I'm just fed up and don't know what to do. We've all talked to him on numerous occasions and yet nothing changes. I don't know what to do.
