Always at the wrong time

I just hate it, everytime when I am talking to her, he comes into the picture. Or, she will do it on purpose. I hate it, the feeling is so horrible. I know I shouldn't be feeling this way, but I can't help it. What if you were in my shoes? How would you feel? She has never spared a thought for me. Instead, she said that I have to accept it. Its really not fair. I fucking hate it! I shouldn't give her all the attention, making her take me for granted. But what can I do? I want to give her the cold treatment but I can't do it. Its so frustrating and I am so depressed. I wish I had no emotions so that I wouldn't feel like this. It sucks big time.
