Is my boyfriend hiding me or am I overthinking?

My boyfriend (24M) and I (20F) have been together for almost 4 months. I’m his first girlfriend ( I’m African) and first sexual partner. We live in a country that’s about 98% homogeneous. He’s incredibly sweet, patient, and thoughtful—if I bring up a need, he always tries to meet it. We spend weekends and some weekdays at his place, and he’s openly affectionate in public. We go out a lot etc.

But when it comes to his apartment, things feel… off. His mom owns his place and sometimes comes over when he’s not home. Recently, his mom organized a cleaner to come early in the morning, and he told me I needed to leave either that night or next morning before 8 , initially he’d thought shed come midday & I would’ve stayed till morning - anyways, seeing as I was disappointed, he rescheduled it to a later hour so I could stay the night.

He also doesn’t seem to mind most neighbors knowing about me—his elderly neighbour ,2 days from his even calls me his wife lol—but one time, we saw his next-door neighbor walking in, and he made us take a longer route to avoid running into her. We still ended up in the elevator together, but the fact that he actively avoided her stuck with me.

My race doesn’t seem to bother him—he encourages me to wear my natural hair, loves washing it and always treats me well—but I can’t help but wonder if race is why he’s being so careful.

He’s never been in a relationship before, so I don’t know if this is just inexperience or if I should be concerned. Has anyone been in a similar situation?
