Wow, that's a really shitty thing to say. Have you any idea of how an abusive relationship works?

Let me break it down for you:

The asshole will be nice and wonderful in the beginning, and then they'll slowly start breaking their partner (victim more like) down. They'll start small, so that it's barely noticeable. The victim won't notice the change because it's so gradual. Their partner's bad behavious is normalized to them. Their abuser will insult them, but phrase it like they should be thankful for the critique. And then they'll work into their victim's head that they (the victim) are super lucky that they are allowed to be with them (the abuser) because no one else could put up with them because they are too (insert insult). And if their partner tells them that they are unhappy they will turn it around and make it about themselves and make the victim feel guilty (even though they haven't done anything wrong), and when the victim breaks down and cry, the abuser will comfort them and tell them something along the lines of "oh you are a shitty person, but I forgive you. You're lucky to have me because most people would have left by now. but not me, because I love you.".

So the victim ends up feeling like they are worthless and even though they are unhappy they can't leave their partner because they feel like they should be super grateful that someone can stand to be around them at all, and that no one else could ever love them. And if someone then critiques the abuser they will get very defensive, because in their eye the abuser is the only one that could ever really appreciate them. They think that without the abuser (that they see as a normal partner) they would be forever alond and no their friends would leave and they would never ever be loved again. If you don't believe me, use google.

Also, I was in an abusive relationship and one of my friends suggested I should break up with him, but I got angry at her because I felt like she was suggesting that I let go of the only person that could ever love me even remotely. Now I'm free from that relationship and I'm in a new one with an amazing guy.

But if it was up to you, I wouldn't have been, because according to you I don't deserve being happy with him. Thanks a lot, you dick head. Go fuck yourself.
