Hard time sleeping!

 now that I'm pregnant is harder to fall asleep at night. And when I do finally get to fall asleep I have to wake up to pee. So I bought my husband an air bed, for him to sleep in.  He's constantly moving and usually talks and plays out his entire day while he sleep. I'm scared he might kick me or something. Was this a bad idea?  When I told one of my friends about it she told me it was rude and inconsiderate. What do you guys think.
