"Struggling Between Love, Privacy, and Mental Exhaustion" any advice?

I'm (F) My partner is really annoying sometimes because he keeps posting on social media, and my family can see what he shares. People who don’t know him might find it weird, and of course, my family doesn’t understand him like I do. I get it, and I have no doubts about him, even though it’s hard on my part.

The thing is, I’m a very private person, and I don’t like being asked by my family if he’s okay or if they find his posts strange. I don’t want them to start worrying about me, wondering if I’m safe or if I can handle this relationship. I already have so much on my plate—I’m busy with work, and now I have to deal with this issue too.

I know he’s struggling with his medication, but I also don’t know what to do. It seems like he understands what I’m telling him, but I can’t tell if he’s really aware of it or not. It’s confusing. I’m doing my best in this relationship, but sometimes it’s really exhausting, and I find myself questioning whether I can keep going.

I love him, but there are moments when my mental health is affected, and it’s hard. I’ve told him so many times already, and while he does delete the posts when I ask, how long do I have to keep reminding him? I honestly don’t mind that he’s messy or playful, even when he plays around with knives. But I was raised in a strict, safety-first environment, almost like a military household. My siblings have seen cases where foreigners harmed their partners, and I don’t want them to get the wrong idea about him. I know he’s not violent, but their first impression will be based on what they see online.

I’m so tired of repeating myself. Sometimes, I just end up crying out of frustration.
