Office Politics spoiled my relationship!

We met on an airplane on our way to our first jobs in a new country. We clicked immediately and became close friends. Over time, we both confessed our feelings for each other. Working in the same office and living in the company accommodation brought us closer, but it also attracted unwanted attention. Eventually, a complaint was filed against us. The company tried to change our shifts, but nothing changed. Once, due to her being accused of wasting time, HR even contacted her family, mentioning us. Since her parents were concerned, I reached out to them and comforted them, promising her father that no more complaints would arise and she wouldn’t get fired. This incident made HR think of our relationship as serious. I was promoted, and with that came increased responsibility. Initially, I struggled to perform. My new manager believed my relationship was a distraction and threatened my job multiple times. Fearful, I started distancing myself from her at work and reduced visits to her accommodation. Feeling lonely, I encouraged her to hang out with others, and she grew close to a senior colleague. I trusted her, so I wasn’t insecure, even though mutual friends mentioned they were getting close. Communication gaps grew, and she started respecting me less. Eventually, she broke up with me over a minor issue of not bringing food delivery and not joining her for dinner during her opposite shift. After our breakup, she prioritized the senior colleague, who supported her during tough times. She claimed she didn’t have feelings for him, but he confessed his feelings to me when I had a man-to-man talk with him. When I told her, she initially denied it but later said he was frustrated, which is why he told me. She went to India for a vacation, and I followed to patch things up, but she ignored me. I tried to show her his manipulation, but she blocked me. When she returned, things seemed sorted between us, but then he got transferred, and she blamed me, accusing me of being jealous.
