What went wrong with the relationship?

My ex and I were together for 2.5 years. He 24 Lebanese man from a very religious family, i 32 Aus with two kids. I was his everything. Due to his family’s beliefs, he wasn’t allowed to spend nights away or have sex before marriage. After 18 months, we were intimate because he said he believed I was the one. He hid our relationship, which caused constant tension. He would frequently stand me up or arrive late. He had no friends, rarely left home except for work, and said he had to take care of his parents—particularly his mother. Despite this, he seemed devoted: texting me constantly, showering me with weekly gifts, and visiting me almost daily.
I bought him tickets to Japan for his bday. He had 10 months and always assured me he’d go, despite me asking over 200 times. 3 weeks ago, my mum even confronted him at dinner, urging him to be honest, and he told her he’d go. Two weeks ago, while shopping for the trip, he asked me to buy him a jacket, which I did.

However, my anxiety (BPD) got me. I went to his house to speak to his parents. They told me he’d never asked to go or arranged time off work. I was devastated, demanding he come and talk. He accused me of being abusive and violating boundaries by showing up uninvited. When he tried to leave, I lost control, screamed at him in public, and put my hands on him. He called my mum, accusing me of being abusive and needing psychiatric help. He then blocked me on everything. Two days later, I sent him a single apology, acknowledging my behaviour was unacceptable and promising to work on myself.
He called my mum again, asking how to respond. This escalated into a heated argument with my parents. My father accused him of emotionally abusing me for 2 years with his lack of consistency. My dad demanded he apologise and get on the plane or apologise and “f off”. My ex didn’t apologise. Instead, he blocked me and my parents and left me to board the plane alone.

did I deserve to be treated this way? Will he just forget me?
