Advice welcome…

I come here since I don’t have anyone else to get advice from so please forgive me in advance…

One of my colleagues apparently have issues with me and I have no clue why. Let’s call her (Colleague A). She’s really different if I say so myself. One day (Colleague A) called my name and I didn’t hear her as I had my earbuds in. She then messaged me on Skype. I knew she called my name because another colleague told me later that day. Before I could read her message she deleted it and since this day she has become a devil lol. When I come in the office I speak to everyone but she doesn’t say anything or barely speaks. One of my close colleagues that worked with us was just casually talking and she told me that (Colleague A) wanted her to come over to her desk and while she was at her desk (Colleague A) kept looking over at a different colleague saying how she needed to talk low cause ppl like to ease drop”. Granted my close colleague didn’t know the other girl didn’t like me… my guess is she tries to make it seem like she’s talking about me since I sit in front of her. Well, she and I both talk to a lady on our team and she will purposely stay behind or avoid me by all means. Idk what it is but whatever it is, it’s eating her up… Today we had a staff meeting and she sped out the room nose up acting like a bitch as she marched passed me. I’m a good person but she is really pressing my buttons and I need my job. Any advice is greatly appreciated.

Edit to add**

Prior to returning to office after 4 years (Colleague A) would text and call me a lot. Now that we’re in office she prefers to text or message me only… seems like she’s 2 faced and doesn’t want anyone knows she talks to me.
