Do you think I am in danger?

I know a girl for years. I thought she was single. She put up half naked photos online and changed her Facebook status to single 

I replied to her social media posts a few times and she replied and we had conversation.

She was on and off with a drug addict and he found out and texted me off her phone trying to set me up, but I didn't see the messages until next day and the girl apologised 

I saw her a month later and she apologised and said on day he thought she was having affair with me because he's hard on drugs but she said we were only friends (she friendzoned me being honest). I changed subject and didn't feel it was worth talking about.

They didn't break up and seemed to have move past it as they stayed together for months after.

It's been almost 2 years. Will that dude bother confronting me if I see him? My friend thinks it sounds like he jumped to conclusions on that day but then saw sense and forgot about it and probably would have attacked me at time, but now probably wouldn't bother seeing as so much time has passed and he very likely knows she didn't cheat on him with me at this stage.

I feel pretty anxious about running into him.

Could I be in danger or is my friend right.
