Am I being overly sensitive?

cts22
One of my “best” and oldest friend has recently gotten a boyfriend. It’s been an on and off things since the year started. I’m happy for her but it has damaged our friendship and how I see her. At the beginning I was having a rough time I would try and call or text and she just simply wouldn’t respond or would call back with him on the line. I didn’t like that because I just wanted to talk with my friend. She stopped calling and texting even more. I graduated bad she came around but I don’t hear from her for big chunks of time. And she says things as if I’m lesser than her or don’t understand things because she has a boyfriend and I don’t. I took the hint and stopped calling etc. even in person when he is not with her she is glued to the phone and can’t respond to conversations as she is texting or calling him. It makes it difficult. I understand being in love. And I’m happy for her but completely shutting me out is off putting. We’ve been friends since childhood. Or is it my own insecurities? Am I being too sensitive? I don't know it just doesn’t feel great. I want some understanding
Am I being overly sensitive?
