How often do your friends spend the night or spend the weekend with you and do you get tired of it?

My younger cousin has been coming over a lot. He has been coming EVERY single weekend for almost 3 months. He has a home. We dont mind him coming over but out house isn't the same anymore. I'm the only female in the house until my mom comes home. She don't come home until 7-7:30pm. Dad comes home at 5:30pm. It's just my older cousin, brother and my little cousin. My older sister loves with her husband. We always have people over at my house but it's mostly guys. My older cousin's friend try to get with me. He was hitting on me and he said, "You look good. I mean it REALLY good and attractive. What's your name?" I told him my name but I wasn't intrested. He said he wants to hang out sometime but I haven't seen in months.....thank god.
Most of the time I don't wanna be home. I used to but I can't be at my house so I HAVE to leave. My little cousin said he got a job around the corner of our house which is cool but he said might considering moving in. Not really but he will be at our house more. My friends ask if he is living with us now because he has been there a lot. We don't habe an extra room and my parents are not doing anything about it! He needs to go back to his own place. Not trying to be rude.
