Need your opinions on this,

Hello, I am a Veteran (US Marine Corps), that was married to my ex-spouse, but our marriage was later annulled, meaning we were never officially recognized as married. During our time together, we acquired a VA home and a vehicle. My ex-spouse utilized my military benefits for the VA home but didn’t contribute financially to either the home or the car. When we decided to part ways, she didn’t claim any rights to these assets, in the annulment she indicated, "No assets or debt" because I had paid her cash for any debt she believedbI am have incurred. Additionly, I offered her the chance to stay in the home if she helped with half the mortgage and costs since it would have become a financial burden for me, she chose to leave and hasn’t pitched in since. Now, she's seeking a buyout after a year and I’m seeking to remove her name from both the VA home and the vehicle due to her lack of financial involvement.

I have evidence I am the sole contributor towards both loans. I have evidence that without my military or veteran status she wouldn't qualify for a VA Home loan or membership with USAA that our Auto loan was through.

Should I fight it? Should I just pay her?

Annulment was approved on the grounds I committed fraud by not disclosing the extent of my injuries I had sustained in the military (My idea), I didn't contest it cause I wanted to get away from her. She was never faithful during the course of our marriage and was just too toxic for me.

The "debt" incurred where just half of the amount on her credit card that she believed I owed her even though it was stuff she bought. I don't really care about that.

She is on both the deed and title of the properties.

Should I fight this?
