I shipped my exes items back to her? AITA

Short context: she initiated the breakup, we were 1 year LDR. We had just came back from our 1 year anniversary trip, since then she spent time with her friends/family then called me 3 weeks after our trip that can no longer continue the relationship because she couldn’t meet me where I’m at. I didn’t plead or beg and shifted my focus on me. Since then it has been about a month of the no contact and I decided to send back her clothes, items (not emotional relationship gifts) back to her. It is currently on the way but I didn’t send her a text about it. Why do I feel so free yet so bad? On the other hand, she caught me off guard with ending the relationship that I decided to not put any energy into it and just heal in silence. Why do I feel so guilty?
