He said to me "It must feel horrible for you to be living in the misery all the time"?

My opinion on this is that he has learned to take advantage of you and this has been making your miserable. And instead of you doing something about it all you do is complain to him and he sees that as weakness on your part. Men do not listen to weakness, they listen to and admire strength in a woman. Trust me, my intents here are not to upset you, because my wish is to help you. Sometimes the truth is the only way towards helping someone. During the time of dating a couple sets the stage of rules from the way they tolerate certain things from their partner. The rules of disrespect are already set in stone by how you have tolerated how he mistreats you. So here is soem advice. First thing you do is see things from his point of view. Picture this, he does not respond to your text or phone calls. You in turn call him and beg him to talk to you, he turns off his phone even though he knows you called. He is thinking, "what is wrong with her, I treat her like crap and she still calls, she has no self respect or value for herself". This is a huge turn off for men. Why not stop doing what has not worked? Stop complaining and instead show by your actions what you will and will not tolerate. Next time he does not call you, ignore him even if it takes days or weeks. For one thing he will not expect this response from you and you will get his attention. When he does call do not give in to the temptation fo complaining. In fact do not bring up the fact that he has not call, let him bring it up. When he does, tell him you simply are no longer willing to being ignored and if he wants to not call you then tell him then don't. In other words your actions should send a message to him that says, you love him and can live without him if you have to. Inner strength is what will earn his respect. Good luck to you!
