I'm too nice.

I've been with my husband for 6.5 years, married for 3.5 years, and we are expecting our first child at the end of this month. A friend of ours was in need of a place to stay while he was waiting to start work. Well he's still waiting, has found a place to live, but can't move in until mid Sept. My husband has made it clear that come 2 weeks until DD, our friend needs to go. On that note, I wish I was not so nice. I now realize I need my alone time, not only with myself, but with my husband. Emotionally I miss him so much and want our guest gone. This is the last few weeks we'll have as a couple. Am I being selfish?
