Update: AITA for giving crappy Christmas gifts and ruining my marriage?

Many thanks to everyone for their support in my last post. I thought I'd send a small update.

First, for those who asked how the deposit on my new apartment was only the $600 I saved on the gifts, it certainly wasn't. I had to dip into savings, but that $600 helped.

My STBX didn't bother reaching out to me after I left until he was served the divorce papers and my lawyer made it clear we're exercizing the pre-nup. Then it was loving voicemails and texts (I never picked up) from him and his family for a few days trying to convince me to come back, which eventually turned to threatening and cruel voicemails and texts when it was clear I wasn't budging.

My lawyer suggested I don't block them so we have evidence of harassment, if needed. Basically, give them the rope to hang themselves with.

But then last night I got call after call from my STBX. Stupidly, I picked it up thinking there was some kind of emergency or something. I barely got "Hello" out when he said, "The rent is a week late." I told him that's strange because I paid my landlord 6 days ago. He paused and sighed dramatically and replied, "No, the rent for here." I reminded him I don't live there and he shouldn't expect rent. Cue his parents both texting me that they're going to sue me to pay the remainder of the lease entirely.

I'm not worried about having an eviction on my record, since the apartment is in his parents' names. When we first announced we were moving to his hometown, they rented an apartment for us right away so we could move right in. They've been renewing the lease each year. We had to pay his parents and then they write a check to the landlord, who has no idea who STBX and I are, let alone that we lived there. Red flag, I know. I'm glad I had a few weeks to prep my leaving since they'd probably use the fact that it's their apartment to kick me out immediately.

Divorce is probably going to be a bumpy ride with this manchild and his psycho parents. Any advice from anyone who's been through it is welcome.
