I broke up my friend’s marriage

About six months ago, my friend was about to get married in an arranged marriage. It was all set up—families were happy, wedding plans were being made, the whole thing. But here's the thing: I didn't think her match was right for her. I know it sounds awful, but I didn't like the guy. Something just didn’t sit well with me, and I thought she could do better. So, I subtly started to plant seeds of doubt in her head. I played the ‘he's not the one for you’ card and made her question the whole thing. Eventually, she called off the wedding. She thanked me for being a good friend and supporting her decision, but I can’t shake the guilt of knowing I broke up a marriage that could have worked. Now recently i’ve been talking to a guy I met on ask bondha. He was kind, funny. We exchanged socials, and hes not my type(appearance wise) but i grew to like him alot. I find out, after a few weeks of talking, that he’s the guy my friend was supposed to marry. The one I broke up. I literally stopped in my tracks when I found out. I had no idea it was him at first, but now I can’t stop thinking about how I was the reason their marriage didn’t happen.

I feel like I’m in this huge mess right now. I’m falling for someone who is a complete stranger to me in many ways, but also, the same person I helped break up with my friend. I’m constantly questioning if I even deserve to feel the way I do about him, given everything that happened. Do I tell my friend the truth? Do I keep my feelings a secret? Should I just back off and walk away from this whole thing? I have no idea what to do
