AITAH for getting a restraining order?

Please read the whole thing before you make any conclusions.

So my husband and I are getting a divorce and he moved out so from here on out I'll refer to him as my ex.

My ex announced soon after moving out that he planned to steal my cats, one of which is my ESA (emotional support animal), and rehome them.

When he said that I panicked because I'm not mentally stable and rn if I didn't have my cats I would either end up in the hospital or possibly kms.

I'm not joking that's how mentally unstable I am rn

It took a while but while I was trying to get the restraining order he did more and more shit that was purposefully messing with my head like taking most of my clean clothes and laundry detergent.

He took all of my sketchbooks except one and he took most of my stuffed toys.

All of these are things that he won't be using but will purposefully hurt me.

I finally got the TPO against him on the 1st and I'm waiting for it to be delivered to him but he knows about it somehow.

Now this is where I might be the AH

All of this is because he threatened to take my cats and I never even talked to him about it but I'm much smaller then him and disabled (I'm in a wheelchair) so honestly I got scared that he'd just force his way past me and take my cats whenever he wanted to.

He's crying on Facebook about how unfair it is that I went through the courts but I didn't know how else to protect myself.

He's now trying to get a restraining order against me and I'm scared that I'll have to deal with that sooner or later but I haven't done anything that's restraining order worthy.

I've texted him a few times but it's mostly been asking him if he's taken my things because that's just what he does.

He threatened me earlier on and I have suspicions that he found out I was trying to get a restraining order against him so he threatened me to make me stop trying to get it.

Obviously it didn't work but I'm worried that I should have just tried to talk to him about it.

He blocked me on Facebook so I'm only learning this stuff from a mutual friend that he hasn't unfriended yet which I find very strange because the report makes it obvious that I have seen at least one of his Facebook posts that he blocked me from seeing.

My ex doesn't have much against me because I've never threatened anyone and I've never texted them in excess or at wild hours of the night so harassment will be hard to prove but I have texted him and my old polycule that are supporting him.

Maybe I just feel like TAH because I still love him but he's posting that he's crying at work because of me and I know that if I get it to be a permanent restraining order it'll go on his record and can hurt his chances at a lot of things.

Having domestic abuse on your record is not an easy thing to explain away but what he's done was enough to get this TPO so it counts as domestic abuse.

I didn't think about how it would affect him when I started this I just thought about how scared I was that I would lose my cats.

I know it sounds like a stupid reason to get a restraining order but I just need him to stay away from my home.

So what do you think? Is protecting my mental health that might recover worth putting domestic abuse on his record?
