Most Helpful Girl
I'm confused. Is this someone you are dating or a girl who is a friend? In all honesty though, these people sound like co-dependent drama queens. I bet they love the whole drama of fighting and getting back together. Let them do their thing. I have a feeling they'll be at it for years.

You're asking what our opinions are about this? How about you ask yourself if this is the kind of relationship you enjoy being in. So, she's going to a theme park this weekend with her ex and without you, her boyfriend? WTF is that about?
And I'm assuming when you say break up, you're meaning they say they're no longer friends? I hope that's what you're saying, because unless you're in an open relationship, you've got some serious bullshit going on there, my friend.
It's like you're being cuckolded while you sit helplessly by and watch your girlfriend carry on with her ex as if they never broke up and you're the platonic friend. And this horseshit about "you don't know what it's like to be in a relationship for 2 years". Are you fucking kidding me? What does that have to do with the fact she's blatantly disrespecting you emotionally and physically? You and her having different relationship lengths should not matter and her giving some lame ass excuse as to why you should let her walk all over you is pathetic.
If you have any sense of self respect and actually want to be in a healthier relationship, I would strongly encourage you to leave her, ignore her and simply tell her to have a good life with her ex, since that's where she seems to want to be.
Seriously, get the f out of there and stay out. She does not deserve you and you definitely do not deserve this shit.
