How to follow my crush on Ig again after I unfollowed him?

So I followed my crush on Ig, he followed me back but I was scrolling down on his account and I saw a photo of him hugging this girl, I thought it was his girlfriend (I'm still not sure) so I just unfollowed him and I remove his follow, now I just find out the girl isn't his girlfriend its his sister ( God help me 😭), now I wanna follow my crush again but im kinda scared he's going to reject me this time , do you think its better for me to approach him in real life? I don't know I think he have feelings for me becuz he always lock eye contact with me and he shows some positive signs, any advise?
