Is this text a friend breakup? Help me with this

So I have been friends with this girl since high school around 2009. We were best friends. Long story short as years went by we were still close and been through a lot together. Breakups with bfs, family stuff, fun stuff, deep stuff, she had a mini stroke I was there for her and drove 2 hrs to be there for her and take her to the dr because she was scared to drive. She ended up moving in like 2016 about 2 hours away from me and we still texted all the time and when she came our way to see her mom and family she would stop and make sure we would meet up. Went up to see her and at the time her bf who wasn’t nice to her and she was really weird about him with me. Like I was supposed to be hanging out with her and him that time and she made up an excuse for him and also made it awkward for me to even be at their place. Now she moved an hour further and a year ago I could sense her getting more distant. She didn’t come to my baby shower because she was “too busy with work even on weekends” meanwhile she always has so much time to take off for other things and get away trips with friends and her now husband who was the not so nice bf I mentioned.

She comes this way to see her mom and grandma and I mentioned months ago to let me know when she is here and we can meet so she can meet my son. She never let me know. She didn’t come to my son’s baptism and I’m pregnant again and she never mentions it. She wished me a happy anniversary a few days ago. And says a quick hello text and I do too each week. Well today I sent her a text to check in and also an invitation to my son’s first birthday. And this is her response to the invitation:

That is so cute and he is adorable. The calendar is locked at work for March and I won’t be able to make it and I feel bad. I’m sorry. I’m 3 hours away from you one way now and would need extra time off work to try to make that happen. In honesty trying to keep communication open by text isn’t working for me. I am very sorry and I hope you understand. You mean the world to me but I do not feel like my time is respected and when I’m there I feel the same way. I know I made the decision to move and that’s made things very difficult.

So I said “I do respect you and your time. You mean the world to me also. Thanks for the honesty. Wish you, your family, & your friends the best always.”

Like I feel her text was so rude. I’m clearly not important in her life and it’s felt like an obligation she doesn’t want just to text me. I don’t understand the meaning of the “but I do not feel like my time is respected….”

Can anyone tell me what they think this means?

If anyone has insight into any of this or just thoughts please share. I think I’m still just like shocked but… what can you do. Clearly she doesn’t want to be friends anymore.. I mean it’s not like it was a misunderstanding because she never wrote back like “no I didn’t mean like I don’t want to be friends anymore” Thanks. . . Why would she not want to be friends anymore.. she literally just texted me happy anniversary a few days ago..
