Boyfriends mom and grandma STILL clean up after him?

Anonymous
My boyfriend is almost 30 years old, owns his own house, and on the outside looks like he is mature and handles his business. He and I started dating 6 months ago. I work near his house so I partially moved in. I go to college as well so during school days I stay in my house near campus, and on days I have to work or on weekends I basically live with him. Since it's the summer I'm living with him fully.

The biggest issue is, both his mom and grandparents know this, yet they constantly come over unannounced because they have keys, and clean up after him. It's really irritating because they'll throw stuff away (like food) or move things (mine included). For example, my dogs food needs to be refrigerated. It looks like human food. His grandma came over and froze it all so now I can't feed him because it's all stuck together and frozen. She also moved my shoes, clothes and wallet. I feel like I have no privacy.

Another time, I was at his house while he was at work and I did not have class that day. I was studying in my sports bra & his boxers when his mom and her husband just burst through the door. I was so embarrassed because I was indecent. I know it's not my house but I they know I'm almost always there. I always feel some anxiety being at his house alone knowing they could just burst in. They wash his clothes, fix his bed, wash his dishes, pick up his house, etc but he's a grown ass man!!!

I'm thinking I should just stop spending as much time over there and not sleep over. It's way too uncomfortable knowing other people are touching an moving my stuff. I haven't said anything to him yet because I know how close he is to his family and I'm just his gf. However, he brought up the idea of me moving in but I'm definitely planning on saying no with this situation at hand. Any advice?
