I hate how I'm so easily replaceable.

Especially when the person that replaced me is irreplaceable. Like I get really close to them and I actually start to open up to them and they end up leaving when I’m already attached. They don’t completely walk out on me, but they might as well since they found someone better to occupy their time with. And the hardest part is acting as if things are still the same between us because they don’t even realize that they replaced me in the first place. It’s having to see the both of them together when in the back of my mind I’m thinking, “That should be me."
