Does the "No Contact" rule really work?

Anonymous
So, a few months back, my ex decided she wanted to breakup because her crazy mother didn't want us dating. (She's 17 and I'm 18) Since she had plans to move back in with her father, she promised me that once she had moved in with him, we would get back together. We still talked with each other, and it seemed like she really did want to get back together.

However, a few weeks ago, I was scrolling through my Instagram feed. I noticed that some guy was commenting on all of her pictures and was flirting with her. After looking at the guy's page, I learned that he was actually my replacement, and that the two of them were dating. It made it even worse that I learned this when I saw a picture of them kissing.

When I confronted her about it, she said she didn't see anything wrong with it, and began to treat me like trash. I was devastated. She acted like an entirely different person, and it seemed like we had never been together.

I then told her that we needed to break things off, and I then proceeded to remove her number from my phone, and removed her from my Facebook, Snapchat, and Instagram. I decided I would go "No Contact" in hopes that she would begin to miss me and regret her decision.

However, it's been 3 weeks, and I haven't heard anything. Does "No Contact" really work to get an ex back, or is it hopeless?
