A Story of my Friend

My best friend is this girl i met in French class 3 years ago. We were really similar to each other and immediately become close. She's helped me through some hard times and I have returned the favor many times.

At a certain point we both had crushes on each other and we were so close most people assumed we were dating. but neither of us new that these feelings were reciprocated until we were both in relationships.

My relationship fell apart within a month, but her's was worse. It became toxic quickly. And everytime she needed to rant at 3, or just have someone to laugj with I was there. I could always tell things were bad when she texted me memes, and at one point we argued from 1 am to 4 am in the morning about who was a better crab.

2 days ago her relationship ended. She texted me first, 10 minutes after it happened, 3 in the morning. So the next morning (Sunday) I came by with Christmas cookies. I stayed for an hour. I love her. But later that day she texted me, it was different this time. She cut herself, and had briefly attempted suicide (my text interupted it, she decided not to) So I panic. I spam her "Are you ok?" and she doesnt respond. I wait 5 minutes and then, thinking she's dead, race to her house. And I mean race. I was going 65 in a 40, ran 7 stop signs and 2 red lights. I thought i had lost my best friend.

Turns out she was ok, just hiding the evidence quickly before her parents got home. I make her swear she'll call me next time.

Today after work I drop by. She is super excited to see me, and me her. Especially after last night.

Then I find out her ex, a way distant one who has been super aggressive to me, stalked her, and spread rumors, has newn texting her. And she is texting back. I'm pissed. I know I shouldnt be, but I'm furious. He has hurt her so many times. And this Fucking Dick is gonna do it again. Now I'm sure the comments will say I'm jealous, and you bet your fucking hats I am. But deeper than that, I'm worried I'll lose her.

Now here's the catch. I've never stopped having feelings for her. What do I do?
