Is it normal for partner to hide you from his colleauges

I have been in a 7 year relationship with my partner, we had our ups and downs like every relationship would go through.

I found out he cheated after 6 years of dating and I forgave him , even tough our relationship took 360 turn, the trust was gone .

So he was remorseful and he asked for forgiveness and he even confessed to his family what he has done to me , since im known at his family, and his known at mine.

because he wants to settle down and Marry me, his family even notified my family

So we always put each other profile pictures on whatsapp so , you can imagine im still senstive because I have been hurt before and trust takes time to come back.

so every time his at his workplace i would call a lot, to check up on him.

I have been to his work place before only happened once,since he was new there, he wanted me to come see his work place.

so he disabled his profile pictures from his colleagues, they cant see who he puts on his whatsapp , i asked him he said he wants to keep his life private, and reason why we fight a lot its cause people will steal our Profile and wish bad things, since we are in process of marriage.

if he disables from friends i understand, friends can be jealous plus they know our personal life, but at his work place his new.

or did i cross the boundry bu calling alot? hence he disabled his pro pic.

n he says his avoiding for his collegues to see me on his pro pic because I am the topic at his work, so he says his saving me the embarrassment

so is he up to something? or what? or his just innocent just prefers his life private? should I be worried.
