27M losing girlfriend 24F and mental peace

I’ve been in a relationship with my friend’s sister for almost two years. From the start, her brother was aware and okay with it. A few months ago, I had no choice but to tell my parents because they were actively searching for a match for me. It took me four painful months to convince them to accept our relationship. I fought through it all, despite being on the verge of breaking up at times, but I held on, never letting her go. Finally, my parents agreed, but they wanted me to involve her parents, which has now become a point of conflict.

My partner, however, has always been hesitant to tell her parents. She considered doing it but backed out at the last moment. Meanwhile, I had to return to my hometown because my father was diagnosed with something life-threatening. His health has been deteriorating, and he is pressing me to move forward with involving both families soon. He believes it will give him peace and strengthen him mentally. This has been adding to the immense stress I’m already under.

Whenever I bring this up with her, it turns into a fight. She insists she needs space and isn’t ready to marry until the end of 2026. I have always respected her choice, but my dad’s condition makes things incredibly difficult. He doesn’t have the luxury of time. At the same time, her brother and mom already approve of us, but her dad still doesn’t know. I’m caught between my parents’ expectations and my partner’s reluctance.

And now, just when I thought things couldn’t get worse, she called me and told me she was moving out of our house today. I begged her to stay, I cried, I pleaded—but she said she had made up her mind. I wish she could have been my strength during this incredibly difficult time, not an additional source of pain. I told her that no matter what she decides, I’ll be waiting and hoping. But I feel shattered to pieces.

Two weeks ago, she told me she was seriously considering marrying me. And now she says, “Get out of my life.” I don’t know how to process this trauma, but I don’t even have the space to grieve. I have to stay strong for my dad.

TL;DR: I (27M) fought for my relationship for two years, convinced my parents after months of struggle, and endured immense emotional stress. My father, who is seriously ill, wants me to finalize our marriage plans, but my partner (24F) refused to involve her parents and has now broken up with me. Two weeks ago, she said she was considering marrying me, and today she told me to get out of her life. She has now moved out, leaving me completely broken while I’m stuck in my hometown dealing with my dad’s treatment. I don’t know how to power through this.
