It can be very stressful on you to take someone in, homeless or not, people can really be annoying in your space and I am speaking from current experience. My girlfriend's son and his long term girlfriend are in my house right now and I almost had to kick them back out on the street due to mostly the girlfriend's behaviors. They are a acting better now, but we have to constantly stay on them about things such a trashing the kitchen and leaving it for me to clean up and constantly trying to boss us around, which is a personality problem with the girlfriend. I was told 60 day limit, they have been here for just over 90 days and I don't really see them getting out any time soon, so I have to decide, do I throw them out and possibly lose a very good relationship with my girlfriend, or do I just do my best, I really don't want to throw the son out, but the girl may have to go elsewhere with her at times inappropriate behavior. I made her cry, I set down the law to her, she has gotten better but it is pure survival instinct knowing that I was ready to throw her out that has made her behave better. Well, I ramble, but just keep in mind you can become the victim very quickly!
