Abuser Finally Got Caught

I'm unsure if this would be the best place to ask for this type of advice. If it's not point me to the correct sub! Buckle up as there is some back story involved to me asking for advice.

When I (24f) was 13/14 (a little bit of a blur with the age) my cousin (27m) molested me. He's 3 years older than me so he was about 16/17 when the abuse was committed.

Around the age 15/16 I somehow disclosed that I'd been sexually assaulted. I honestly cannot remember how I ended up disclosing this information or what lead up to these events. I went through a place that specifically deals with these types of cases. I did a very lengthy interview with a therapist. I described EVERY time I was molested, by who, at what age and to what extent it went to. I was unaware but it was video tapped and my mother was on the other side of the glass.

This opened an investigation against my cousin. Because it happened in a completely different county (were in Texas) than where it was reported it took awhile for the investigation. At the end of it all the DA closed the case and chaulked it up to a "he said/she said". My cousin apparently said I forced myself onto him and I started everything. I just dropped the idea of ever getting justice and just thought that one day he will pay for what he did to me.

I found out this morning that my cousin was arrested on 11/23/24 with the charges aggravated sexual assault against a child. I cried, I was happy and hurt at the same time that 1. he finally got caught but 2. he took another child's innocence away from them.

My question is: Would it be worth calling the DA for that county and ask if I could testify against him? I don't have proof he molested me but if it meant he actually gets procescuted this time I would love to get justice for the child he assaulted. The actual abuse happened 10 years ago and the case was opened maybe 8 years ago..I don't want to open any past wounds if it wouldn't be worth it. I just want to see the son of a bitch rot in jail.

TL;DR: i was molested by my cousin 10 years ago. He was arrested 11/23/24 on aggrevated sexual assault against a minor. Would it be worth calling the DA of the county he's in jail in to try to testify against him?
