I'm in a relationship with my friend's ex.

Last year during my sophomore year, I had a massive crush on some guy. Then one day, I sat next to a girl in history class. We ended up talking a lot and we became friends overtime. I told her about the guy I liked which happened to be her ex. I felt guilty and shocked, though she did tell me it was alright since she liked someone else. I obviously felt relieved that she didn't mind, but it still felt wrong. Me and the guy had been talking, and his seat was right behind mine. A few weeks after, she found out that the person she liked already had someone. She felt devistated. And before I knew it, a few months passed, the guy started being distant, and everything felt off. Then she confronted me that she came back to her ex to feel comforted and loved again.

I had to get rid of my feelings for that guy since obviously, she (my friend) was first, and that was her ex. During those times, her feelings were turning in and off. She told me that the he (the guy) didn't match her standards and was boring. Soon enough, time passed and we're now third years. During summer vacation, she's been telling about how much she's gone bored with him. Since he didn't really match what she wanted, she broke up with him.

Then, summer break ended. The first month was fine, and there was nothing really going on. Me and the guy started talking in class and pinched each other on the hips in a teasing way. Then one day, he sent a video on tiktok and we started talking a lot. Those simple short talks became a daily routine and got longer as each day passed. Before I knew it, I gained feelings again. I felt guilty since he IS my friend's ex. I told some of my other friends and asked for advice. For three months I've been struggling with my feelings. I told myself I'd move on, but it was harder than I thought It would've been. I couldn't be friends with him and talk with him each day knowing that I'm so crazy over him.

Then friends encouraged me to confess so I could move on. And when I did, he liked me back. It was so totally unexpected. Now we're together and we're doing great. Though I already talked with my friend about it, since I was absolutely terrified when he also liked me back. I felt guilty and stupid for getting together with him knowing that him and my friend had a past.

Me and my friend are now okay, and our friendship's still ongoing. She told me what she felt, and I told her what I had to. But me and the guy's relationship spread, and my friend's new partner had a friend group. That specific friend group hated me since I broke the girl code. I was shocked they knew, but it was honestly my mistake.

What do you think I should've done? And what can I do now to fix things. Please give me your honest opinion, I literally cannot get them out of my brain and I guess that's also on my part.
