I'm glad you're getting out to see your friend. I hope you have a lovely time!
I'm not sure about the schedule thing. I know when I go from living alone 8 months of the year to living with my family whose schedules are SO different from mine, it can be really frustrating. Have you talked to your boyfriend about it at all? Maybe you could compromise -- he could use headphones, book lights, etc to reduce some of the disturbance, or maybe you could try ear plugs/eye masks when you go to bed? The six people in my house are ALL on separate schedules and we've found some of those things helpful.
Also, how are you around other people when your boyfriend is around? Are you more comfortable talking to others if he's with you? I know that I'm a lot more at ease in social situations when I have a friend with me ... in that way, it might help you get to know more of your classmates if you feel more comfortable in the group setting having him there. On the other hand, if you think the opposite will happen and you'll wind up spending all your time with ONLY him in class, then maybe taking separate courses would force you to get to know other people instead? I know it's hard, I have some mild social anxiety of my own.
Anyway, I hope some of this helps and have a good time tomorrow!!
