I don't think you're a bad friend.

I have had to let some "friendships" go because I eventually grew enough to recognize that they were not supportive or mutual. That is very hard if (a) the friendship or tie is long-standing; you have a "history" together and (b) one doesn't have many friends and (c) one lacks self-confidence to believe that there will be other, better friendships.

Just know that it's not you, she is not being reciprocal.
