Open Question: Was I a bit rude to her?

I sort of feel bad for her but I’m just disappointed and somewhat disgusted by her.

I liked her, rejected me three/four/fives times? Broke my heart. Never invited me to any parties or concerts/music festivals. I bought her a necklace from Mexico. Treats me like s**t afterwards. Lies to me that she has a boyfriend

A month later I get a girlfriend with a Portuguese girl, much more pretty, younger, nicer and more friendly

Guess who comes running back?

Now ex is mirroring everything I did for her. And is even posting old photos of she and I when we went out to homecoming. But cus I have a gf now it’s so awkward.

How do I make her stop?

We recently had a talk and I even told my ex «you’ll always be my first love, but I’ve found someone else now and I’m not gonna chase after someone who’ll never love me back.»

Her reaction was priceless. That stupid mug of a smile, gone.
Ex: oh………………… Hmm well I was actually going to ask you if you’d like to go out sometime but it doesn’t matter anymore. You don’t have to anything you don’t want to but-
Me: But what?
Ex: doesn’t matter…
Me: you’re pathetic

She walked off obviously upset afterwards. I just shook my head in disgust.

Did I do the right thing?
