Why do people ruin something good they have

If you claim to want communication, yet refuse to tell your partner what's going on, then you can't claim you want communication.

Why leave them on read for hours/days? 

Why purposely ignore your partner, yet be able to talk to other people?

Why ask "are we ok?" If you're the one ruining the relationship?

Why would you make your partner feel like they don't matter to you? That you show by your actions that you have no problem not talking to them? That you are totally fine with making your partner feel like you don't want them, that you don't care about them, that they don't matter to you?

Why claim you love them, but your action say otherwise?

If you don't want to be with them, tell them, stop playing with them. You probably don't want too cause you know you have someone Amy and you don't want them to leave... unfortunately for you..you have successfully ruin our relationship, claiming you want to be close like we were but keep me at a distance...law of physics makes the impossible...don't ever claimed you loved me cause you showed that you didn't.

Man..this felt good to type. It made me feel more free now
