once again i have hurt ur feelings

I dunno wat to do? someone pls teach me wat to do. I am just trying to help her and be her best friend but all i know is i have hurt her again. I can see that everytime i appear in front of her, she will feel uncomfortable. This friendship will really end here?? I hope it wun but all i know is she will leave our group soon and wun mix with us anymore. Is it really because of me or there are other reason? Should i just stop messaging her and just ignore her or continue treat her like a friend? What should i do??? I am so confused and i cant make any decision anymore. I dun wan to hurt her feelings anymore. All i hope is she will be as happy as last time.
