I need help with a decision

So there was this girl who seemed like she liked me. She would like every single photo I would post and comment something. About herself and her friends unfollowed me (I know it sounds kinda childish) and I've been contemplating whether or not to ask her out now. I've always wanted to but I didn't feel ready, but now I do. I've been feeling really sad about it like I have hurt her, now I have a feeling that if I did ask her she would reject me... I have no idea what to do,if anyone would be kind enough please help me out a little bit.

She/they may have unfollowed you because she/they sensed that what you wanted was inappropriate for her. Get a message of apology to her for coming across a bit intense. She will get back to you then, should she wish to pick up on the friendship (friendship only)
