My boyfriend deleted all his posts of us, should I be worried?

My boyfriend had 4/5 posts on his instagram and they were all of me and him. A couple of weeks ago he deleted them all because they “didn’t fit in” and he wanted to “start fresh for summer”. He has my name with a heart in his bio, but everything of me is deleted. He has posts of me on his vsco, but his account is private and only his friends know his username there. Since he deleted his previous posts, he has posted 4 new pics and they are all selfies. I have one post on my account and he is in it. We’ve been together for almost 9 months, and he deleted everything of me almost 1 month ago. The pictures he deleted are of us since the beginning of the year, and he used to say that they were his favourite pictures of us and that he loved looking at them. Im not sure if i’m overthinking this?
