Will my ex-girlfriend miss me after her arranged marriage?

I started a relationship with a girl. First we thought it just a relationship no marriage. But as days going we fell deep into each other that we cant live without each other. I found one thing that she loving more than needed. Im so scared of her, what will she do if i run out of her life for my marriage. This thought killed me. So I decided to leave her without telling a reason. I left her with a small issue. I really dont want to loose but i had to. I just said good bye, she also said good bye. Later i never texted her. She too never texted me. But after 2 months i felt guilty of leaving so i came back to her. Previously her parents decided to marry her to their son in law. I know this when were in relationship. So after our breakup i came back to her. But she said no to me because she is committed with her brother in law. I cant take this. Its killing me. After i said good bye she never tried to contact me for patch-up. Even no texts. Her brother in law told her that im ready to marry you. So she too said i too like you and im also ready to marry you. But their marriage will happen in 2026. I told her that untill marriage please be with me and this is our deal when we started our relationship. But she said no. I begged her many times but she always said no to me. And still now i cant believe that she said no to me. All this happened 3 months ago but still i cant forget her. Recently she deleted my number also. Everything making me feel low. What should i do now?
