I feel abandoned by my friends, specially one person.
For years, while she was alone [was not in relationship], I didn’t plan even one trip or event, without making sure if she is comfortable. I wanted to make feel not lonely.
Meanwhile other friends went on with their lives and just sometimes checked in with us. We used to talk about that it is so rare occasion to meet them. Now when she is in relationships, I see her, and those rare friends plan events together.
They include me also, but it is more like after they have spent some time together, they remember to include me. I feel more like obligation [for old times] than friend they want to spend time together.
