Crazy people!

So I made a friend at college and thought she was awesome.

We talked for quite a few months, hung out, and I kinda started trusting her and confiding in her as a friend. She was really sweet.

Well. Now she's psycho. Blowing up my phone because I didn't answer her, threatening suicide because she felt like I was ignoring her, etc. Etc. So I told her we just needed to not be friends. I can't handle all that mess. She went even crazier. Harassing me, blowing up my phone, contacting my friends (people she didn't even know. She found them on social media I don't know how I never gave her that information and I don't have social media so I know she didn't get it from me!) And harassing them. Now she's contacted my fiance and is telling him I'm cheating on him (I'm not!) Get this....with HER!! OMG. Nooooo...!!! And she's sent him screen shots of our conversations and is trying to twist things. Thank god he knows how I am. (I call everyone love/babe/sweetheart, and I'm very flirty, even if it's platonic). But I'm just freaking out that she had access to these people and I never even told her their names or anything, and she's found their social media and everything! We've all blocked her but there she is again! Omg.
