This house stuff

So, this living situation thing is really stressing me out. So, Lauren and I are SUPPOSED to be moving in together when I go home next Saturday. As much as I want to do it, and as much as I love Lauren, there are so many things in her life that I just can't get down with. I can't stand her drug use. I mean, I know it could be a lot worse but regardless of what it could be, I just don't like it. Period. I hate the smell of it, I hate how she acts on it even if she is acting rationally and I just don't like it. I guess how I feel about her woo use is similar to how some people feel about Marijuana. I don't know if I can live in a household where that's being done. On top of that, her relationship with her exes really bugs me and i don't like it. Namely with Shawntee, I fel like Shawntee is incredibly manipulative and adds nothing positive to Lauren's life except that they frequently smoke woo together and that Lauren is close to her family. Shawntee is not doing anything with her life and Shawntee & Lauren are talking constantly and it really bugs me that, especially when I'm in town for weekends, Shawntee insists on calling multiple times a day and it just bugs me because I feel like she should respect the fact that I'm in for the weekend and Lauren and she can't talk as often as they usually do. I guess I want so bad for us to keep progressing and I'm afraid that I can't deal with some of the things she has to offer. I have been incredibly quiet and subtle about her smoking woo, but as things could potentially get more serious, I'm afraid I can't handle it anymore than she has to offer. I really want to tell her "quit now, or I leave" but I know that won't work. I feel like she's constantly choosing the drug over me. I hate that Shawntee is such a shady person that Lauren wraps herself into. Her and Shawntee have the same dependent relationship from when they were together and i can't stand it. I don't think Shawntee should be allowed to smoke in our house. To be honest, i don't think Lauren should either. I don't trust that - after I leave for break - Lauren won't have her exes spending the night to "keep her company". I just don't know if I'm ready for this moving in thing until I'm permanently home and out of school. I just don't know if I'm as ready or I can handle all of this as well as I thought.
