I'm kinda insulted that my friend didnt follow me back on instagram?

[Jenny]

There is this girl I knew since kindergarten and we've been best friends forever, we haven't talked in a while (4 months) and I found her on instagram so I followed her, she had to accept the request and she did but she never followed me back, she is following over 200 people and has 40 followers and she didn't follow me back, I know it's not that big of a deal but I'm actually really insulted. Some people don't follow back because they don't like your pictures but my pictures are basic selfies and cool pictures of nature which knowing her she wouldn't mind. Idk it just really bothers me ps it's not like I post alot of pictures maybe once a week
