My ex and I are working on things and he hasn't been answering my calls and texts all day. He's currently working 2 hours away and I was so hurt by the break up that this scares me. I know he saw my texts, call and voicemail but he just hasn't responded. I ended up having a panic attack earlier today and it terrifies me so much. I want to make this work but if he's not making an effort maybe I should walk away?
