Hi, thanks for replying.
He is my ex, I thought we were working through to getting back together. I guess I was wrong.
he doesn't want antidepressants, he believes that if people have been getting through this for centuries why should he need antidepressants? I don't want to force him to take them, I will be asking him about counselling if he will see me soon.
I haven't read Anne's books, I'll certainly look into that, it's so painful going through this.
I want nothing more than for us to be back together again, I feel like he's keeping me hanging on and won't make a decision to just get back together and face this as a couple. 
I never know what to text him when he's like this, I feel like I'm walking on egg shells, is this normal? Is there any way to stop him pushing me away?
