She's upset I don't consider her a friend

I get everyone has different definitions of friend, but imo for you to be my friend you have to continue to talk to me. I had this girl I was friends with and she she had a baby which is fine. But she kind of talked to me less and less and left me on read a lot. And I get it. She has a baby. But the last time we talked before this was 6 almost 7 years ago. I invited a small group of a people to a private wedding ceremony me and my husband were having. One of my other friends reached out and asked why this girl I no longer consider a friend was there and I said we just kind of grew apart and aren't really friends anymore. Then told that girl(stupid high school shit) and she messaged me asking why we aren't friends and she's hurt I didn't invite her. I said we don't really talk and she said "I'm sorry I'm a mom now with responsibilities and can't be on your beckon call". I was like .... Girl you haven't spoken to me in almost 7 years. I get being a mom is hard, but if you can't find time to talk to me for almost 7 years then maybe we've just out grown the friendship. Am I wrong?
