Ending a Forbidden Relationship and Finding Peace

Assalamu alaikum. I’ve always tried to steer clear of relationships outside of marriage; it just hasn’t been my thing. But last year, I slipped into one, and the guilt has been eating me up. It was tough to walk away because I didn’t want to break his heart-he seemed so deeply invested. I kept making dua, asking Allah to guide me out and, if it’s meant to be, to bring us back together in a halal way someday. Then a few days ago, something happened that gave me the push to finally end it. But oh, I didn’t realize how attached I’d become. I had built this whole future in my head that will never happen. I feel so heartbroken, you know? When it first ended, I felt relieved and thankful that I got out before things got worse. But the next day, the missing him hit me hard, and I couldn’t stop crying. It’s like a rollercoaster-one minute I’m at peace and cheerful, the next I’m sobbing with a heavy heart. Just yesterday, I thought I’d finally moved on; hope filled me up and I was almost certain I was over it. But today, I woke up thinking of him again and cried after a while. Even now, my heart aches. It’s only been a few days, so I get it. But how long is this going to last? When will I know I’m truly healed? Could a sister who’s been through this and moved on please reach out? I really need some support or advice right now.
