My best friend and fp of literal years has started a new college program, and between this and timezones, we barely talk. She's been making new friends. I know I should be happy for her and I am, especially because I know she was upset about not having many friends before, but I can't help that constant "So I'm not good enough for you?" Like, Heaven forbid she want more than one friend. 

She's definitely picked up on my feeling this way (she knows about my BPD) and is responding by sending me affirmations of her love for me, etc. But those annoy me, too, because I feel like she's only sending them to keep me occupied. Today, we barely texted, and every message we sent was just fake feeling "I love you!!" messages, as compared to before when we could text for hours on end about anything.

I'm having a ton of trouble not analyzing these recent changes as a sign that she's about to abandon me for someone else. Advice or commiseration appreciated.
