<human>: Can you condense the text into a few key points?

I dated a girl for about a year, until I had to move for school, we became distant over the course of 2 months or so and she broke up with me. I didn't care at all, until a week later she slept with some dude but she lied about it. Twice. I tried cutting her off but she was destined to prove her affection to me and vowed to do anything she can to earn my trust back. Recently, she had been admitted to the hospital on account of her depression getting very bad. She's doing better now but I still have major trust issues and she cried to me apologizing and telling me I make her happy and she loves me. I want her too but I feel like I lost all trust and I'm very hurt about what she did to me. What should we do?
<bot>: ex broke up with me, hurt me, i tried moving on, she really wants me back and i am lost and confused.
