<human>: Can you give me a shortened version of the text?

First with the backstory:

Back in April, my ex (who I had broke up with last year in July) got me to come over to his apt because he told me he had paperwork he found that I needed. Stupidly I went alone, at night, and ended up getting raped and strangled by him. I went to the police and reported it, they looked into the guy for stuff, and it turned out he had a past against a little girl so I took my kids all in to see a therapist that specializes in that sort of thing. Found out my oldest was molested by him. 

So they were working on my rape case. I had gotten a recording of him admitting to raping me, and stalking me, and gave the detective all the messages he had sent me in just two weeks- which was A LOT (facebook, Skype, phone messages, email) and they were going to pursue the molestation case separate once my daughter had time to tell a therapist what exactly happened. 

Now for my question:

I got a call from the district attorneys office saying he had agreed to 100 months in jail for rape if we drop the case with my daughter and they were asking if I was ok with that. I was confused and asked questions, and eventually agreed to it as long as he had to register as a sex offender and be put on searches so other mothers will be able to find him if they look (he didn't pop up on searches when I first started seeing him). 

My question is should I have pushed to get the case against my daughter tried? For my rape case I have the audio evidence of him admitting to everything, the calls to 911 when he would randomly show up at my work harassing/threatening me after the rape, and 100s of messages from him that he would spam me. So I would think they'd be able to get him no problem for the rape. 

I just don't know how legal things work and want my daughter, and all other kids that could come in contact with him to be safe. I guess I'm just worried about what he could do to others if I don't do what I can to stand up against what he did.
<bot>: My ex raped me and molested my daughter and I agreed to him just getting max time (100 months) on the rape if the molestation got dropped. Did I do the right thing?
