Should I be concerned?

So basically I really like my bestfriend and she says that she likes me. Problem is she had a boyfriend for 2 years and she broke up with him last January. He is honestly crazy...he drives by her house at night to see if anyone is over there and he constantly texts her saying he misses her and even sent her flowers a month ago with a note saying how much he misses her and loves her. She claims she doesn't like him anymore and likes me but I am still concerned. To top it off her parents liked me when we were just friends but now they hate me claiming I sabotaged their relationship. What should I do?

If I was in those shoes, I would confront her.
If you done nothing wrong at all. (trust me I had my share of time I wanted to interfair with relationship. I don't)

Talk to her, confront her, and lay off.
Let her think about it.
I tried to win this girl over after this guy broke her heart. I really like her; we get alone fine. Well I became toomuch into trying to talk her away from him. I messed up. I left her alone, guess what she text me "h"i and now I know we are still friends.
I talked to her 2 days in a row just texting but left her alone so now I am waiting to see if she talks to me 1st if not I will ask her about some hobbies she has.

So I would give her space and time. If she really likes you she will come around in time.

If she doesn't talk to you anymore, hate to say this she never was a sincere friend. Move on. I know it's hard. That's the best I got. So good luck.

A relationship that that's working can't be "sabotaged." She had two years to figure out that she want to be with him. Why do you feel you need to do something?
