<human>: Could you distill the essence of the text into 1-3 sentences?

My good friend of many years has hit a rough life patch and is looking to make living arrangement changes following the end of a bad romantic relationship. The start of her new lease doesn't begin until March, so she is hoping to move in with my husband and me through February.

It's been a long time since I've had a roommate other than my husband, and I'm concerned that this change will negatively affect our marriage. On the other hand, turning my friend down also concerns me, since she doesn't have many other options, and I want to support her as she looks to make a positive change.

Has anyone taken in a roommate after marriage? Any suggestions for good boundaries to set or questions to ask in advance?

Thank you very much for your help!
