AITAH for wanting to end the friendship completely?

I had a best friend, Sam, who went to the same professional school as I did. After graduating, I went straight to working in the profession, Sam did not.

Sam and I kept in touch, and she wanted to work in the field I was in! So I got her a job at my work place and everything was great. I ended up branching off & opening my own business. Sam stayed at the job, got pregnant & I decided to help her open her business. I offered my work space & let her use everything that was mine.

My family & I decide to move across the country. I gave Sam as much notice as possible (at LEAST 2 months). So that she could do what she needed (either find a cheaper place to rent or stay). I offered to help by hiring someone. That didn’t work out. Sam, did not get along with the owners of the suite I rented from. She sent me the things that they told her and I agreed. It was aggressive but firm. She took it as mean. But I did agree with her. I sold Sam all of my professional equipment and decor at a very discounted rate and lots of it was free, so she wouldn’t be in a pickle. I tried to help her as best as I could. But she took it very bad, even though I tried to help her as much as I could. And of course I sent all of my clients (people I had a relationship with, and seen them every 2 weeks for years). In the end (about 2 weeks after I moved) she moved out of the suite and found some place cheaper.

4 months pass, and my family and I decide to move back. Sam knew I was unhappy where we were and I told her so many times that I missed my clients. I also kept her in the loop as much as possible. I was unsure of where to rent. But ultimately decided to go back to the suite I was renting from (where she did NOT get along with the owners). Out of familiarity. And I genuinely LOVED my suite. I also talked to her about clients and vented to her about how I’m sad they wouldn’t be returning to me. And that she was great at her job. I was venting a lot. Keeping her informed of every single thing.

Sam started getting distant. She started posting on socials with my clients (she is not active on socials) and just being weird with me, as the days lead up to me moving back. There wasn’t any mutual support on socials(me recommending her, she didn’t return the favor). I asked her about her distance. And I said that I had felt like I was being too open and honest with her and that im sorry if I said anything offensive. I offered her words of encouragement and that I appreciate her

When she finally replied, she said that she felt like I didn’t care about her feelings by moving back to the suite I was renting & that she thought I wouldn’t have chosen to go there based on how she felt about it. She said I made her feel less than when I talked about clients (who were mine and I did work hard for-but I did understand why they were staying with her). She said she was questioning our friendship. This hit me hard. And I processed this for a long time. I started really thinking about her friendship & how not once did she open her new suite for me to work out of (I would have done this), she didn’t ask if I needed help, she didn’t communicate with me about what I said was making her feel, she posted clients, everything started adding up to the point where I felt like I was a hindrance and that she actually didn’t want me to come back. I feel so hurt because I had given her so much of me and my business, that now that I needed help, she was no where. I apologized to her and let her know I didn’t mean to hurt her and that I felt sick that she let me do so and let it brew till she grew resentful. And I explained how I felt. She completely disregarded everything I said about how I felt and kept talking about the things that I said and that it was the principal of me going back to the suite where the owners are “mean” to her and that the friendship isn’t what she thought it was? But I feel that way also, I thought we could tell eachother everything with no judgement and we had agreed a LONG time ago that if any of us said anything that made us feel weird, that we’d speak up. I feel completely abandoned. I moved across the country, only to come back, where is my friend?!

Please help me understand if I’m the asshole. I feel so lost. And I need neutral opinions. THANK YOU in advance.
