I Am Loyal to My Friends

Lately, I've felt like my closest friends just don't want to be around me. They make plans right in front of me without inviting me, ignore me when I speak, and they never defend me when something malicious is said about me. The other day, one explicitly told me that he didn't want me to hang out with them. It's so difficult to handle, because I love and value all of them so much. I don't know what's happening, but I wish it would stop.
