<human>: Alright, so I am 21-f, my SO is 22-m and my housemate is 22-m as well. I have known my roommate for about 3 years and we are extremely close. We became roommates in February. During our friendship, I had never had a boyfriend because I didn't really date. However, when I met my SO that changed. I loved him the moment I met him. He's sweet, funny, down to earth and he's amazing to me. I have never loved someone like this, Reddit, and he loves me just as much. 

Now to the nitty gritty,
My Roommate is a great person, but ever since I started dating my SO he's changed. My SO and I have been together for almost 6 months now and ever since then my roomie has been very rude to him and myself. He constantly rude and short with him and usually has some sort of snide remark. 

My SO is nothing but nice to him, he tries to reach out to him. He went to a movie with him, constantly invites him to stuff and even offered a job within his company. I have tried to talk to my roommate about how he treats him and he usually says something like "I'll be nicer." but he never is. He told me that since I started dating our friend time has been cut down and we don't hang out as frequently. I believe that is true but I also feel becoming roommates attributed to this.

I don't know what to do. I'm afraid that eventually this will become too much for SO to deal with and he'll walk. I'm also afraid that this might end my friendship with my Roommate. What should I do/ what is your take on all this, Reddit?

Give me a shortened version of the text
<bot>: My roomie is rude to my SO who is very nice to hin and I'm worried it will compromise my relationship.
