Avoidant discard question

ever since my avoidant ex boyfriend broke up with me back in march i’ve been thinking back on so much and part of me thinks that he said this to me as his way of telling me he avoids accountability for his actions because we were in a long distance relationship from October 2024 to march of this year and upon me meeting him for the first time when he flew to see me for my birthday he told upon seeing me for the first time that he blocks all his ex girlfriend’s after a breakup because he does that in order for his future relationship with a girlfriend who wouldn’t like it if he was in contact with his ex girlfriend’s fast forward to march of this year after we started talking about planning a future with him and me moving to texas to be with him he started picking fights with me and starting my character and told me that i don’t care or put in the effort when i literally have put in the effort by flying to see him multiple times, bought him custom made pillows with our pictures on it and a framed photo of us and told me i have done nothing to show that o am serious about our relationship when i literally made a huge commitment promise to him that i am willing to move to texas to be with him and he sent me back my toiletries that we both agreed i could leave there so i didn’t have to keep taking back and forth and when i asked him about it and asked if we were okay he said yes only to dump me via text and ghost me afterwards which makes me think this whole story about blocking all his ex girlfriends for his next girlfriend is just a cover up story to avoid accountability for his actions. what do you think?
