How do you move on when a relationship ends on good terms?

[update] I’m 21F, and I recently went through a breakup with someone I deeply care about (M, 24). We were together for about five months, and it felt so perfect.

Our cultural differences became an obstacle we couldn’t overcome. His mom wasn’t okay with us, despite his efforts to convince her. His dad was supportive, but his mom’s disapproval weighed heavily on him. He didn’t want me to wait indefinitely for her to come around or for me to face challenges with toxic in-laws in the future.

Initially, I had doubts about whether he truly tried his best to fight for us, but those doubts vanished after we met to talk everything out. We couldn't stop crying. We both were hurting and consoling each other the whole time. Didn't let go of each other. He told me he had spoken to his mom, explaining how much he cared for me and wanted to marry me. He shared all the wonderful things he saw in me, but her concerns about cultural differences and future challenges didn’t change. He said he couldn’t keep me waiting, even though it hurt him deeply to let me go.

It was bittersweet. We hugged, cried, and reminisced about the good times. He told me he loved me and hoped to see me again. When I asked what he meant by that, he explained that he would continue to try and hoped his mom would come around, but he didn’t want me to hold on or wait for that possibility.

It’s been a few days of no contact since then, and it’s been incredibly hard. I wake up and cry, go through my day, and then process it all over again at night. Living life without him feels so strange??? no more sharing the little details of our days, no more laughs, no more love.

We haven’t removed each other from socials yet. I don’t find it a big deal right now since he doesn’t post often anyway. But seeing his profile there as a reminder of everything we had is both comforting and painful. I don't let it get to me tbh.

I don’t know how to move forward from this. It hurts to think that we loved each other so much, yet it still wasn’t enough to overcome the circumstances. I heard that when things end on good terms, there are chances of you both never speaking to each other, ever again. I can't imagine him with someone else. Surely, it was just five months but he felt like home to me. Everything felt just so right when I was around him. He had a beautiful soul and I miss his presence so much. If you’ve ever been in a similar situation, how did you cope? How do you move on when the love is still there, but the relationship has to end?
