Need to Vent / Advice Please

As-salamu alaykum, wallah i don't even know why i'm posting this but i need to get it off my chest. I've been talking with a sister for a short while, but we'd known each other for over a year. We discussed marriage, so for the sake of Allah we tried to stop talking. After about a week we slipped and started speaking again, and soon after something happened that made her feel betrayed. She's hurt and no longer sees the future we once imagined together. Wallah i've never felt this kind of pain before - it feels physical - and i honestly don't know how to cope. It's my fault, but i never had bad intentions; it was more a misunderstanding. Lately i've been trying to change how i view the situation. I think maybe i was getting too attached, and perhaps Allah is testing me so i can learn to let go. Maybe one day we'll reunite, maybe not - i really don't know, and i don't think she sees that possibility. I want to detach, yet at the same time i can only picture a life with her. Maybe the reason i'm hurting is that this pain is the only thread that still ties me to her. I feel exhausted, but i trust that ease will come eventually. I've been praying tahajjud and trying to draw closer to Allah, but wallah whenever my iman was strong it was often influenced by her in one way or another. I just needed to say this aloud. Please, i don't want platitudes - keep it real and give honest advice, insha'Allah. Or maybe nobody reads this and i'll find it later. I think i need to place more trust in Allah and soothe my heart with His remembrance.
