There really was no positive way to look at it, though Tina would never place all the blame on Mike. After all, it wasn't like she was trying to punish anyone. She just honestly thought that this was the best for everyone. The thoughts had gotten so dark, she needed to get away from them. But drinking wasn't the answer to that because she would get sober and probably realize she'd said something idiotic. No. The only way to silence the dark thoughts was to give into the pain and take her life.
The pain would end. The uncertainty. The self loathing.
Really, it was a myriad of reasons. But Tina was in and out of consciousness so she couldn't explain that to her boyfriend. Not like he'd want her after this. No, she just wanted to fade away. The others would forget her. And who knew, maybe the way to return home was to die in this world. Maybe she could go back and have her boyfriend. All she had to do was die here. But Mike wasn't letting her. She had no idea what was going on. She was aware of jumbled voices and coldness but that really was about it.
When she was bandaged up, Tina weakly reached out and held onto Mike's hand. She was exhausted but she wanted to somehow convey that she was sorry for putting him through this.
