Am I overreacting or what? DIL question?

I just got married 4 weeks ago. We dated 3 years while his divorce went on for 4. (I year prior to me meeting him). Please don't comment on that I know many of you will say "that what you get". Mid March at the divorce hearing the judge recommended 650/month spousal rehabilitation for 2 years. His ex called daughter who made many rude texts,voice mails, FB'ed me, my family and friends about how horrible I was and how her mother deserved more than 650. There were even a few physical threats thrown in just for fun. About a month later daughter told Dad she was sorry she acted this way and they reconciled after an almost 4 year separation (daughter took moms side). Dad was thrilled. Daughter talked him into quitting his job and coming to work at her company (same business type) where he would make so much more money. She was making 4.500/month working just thurs and fri, Dad (my husband) decided he needed to work there for the money and to help improve his relationship with his daughter. 3 weeks later she quit because she wasn't making enough money (she lied about the 4,500). He is now having to go back to his old job since she completely lied to him about the money. I feel like she set up up to hurt him financially since she knew he would make less than half of what he made. She also knew that he was going to have to pay her mom the 650 and it would not be possible at the new job. While they were working together and until the divorce was final she remained very close to him. meeting after work for happy hours, dropping by with boyfriends, asking me to be on the emergency pick up list for her son at school. She was "best man" at our wedding. We got married about a month after the divorce was final because we wanted to. The fast (5 days/12 guests) wedding was not just because we wanted to get married but I was having surgery that would lay me up for 4-6 months. My husband was also facing deployment on a disaster (non military). We decided that we would rather get married then instead of waiting for at least 6 months. Also, if something happened to him while deployed I would get his benefits (which his ex would not of anyway) We have seen her 1 x since the wedding. My husband was deployed to the disaster and is living in a war zone where daily shooting are happening. She knows this and has still not bothered to call him to see if he's ok. He had to take the deployment to make enough money to pay the bills and catch us back up on what we spent out of savings for him to work with her for 3 months (even though she quit). I feel like she intentionally set him up for a major money loss knowing how much more it would hurt him since he had the added payment to his ex. I tried to talk him out of changing jobs because I don't trust his daughter (esp. after the treatment and threats following the divorce hearing) and I thought she was setting him up. He doesn't agree with me. Shes his little girl and wouldn't do that to him. Regardless since she is his daughter I will always be nice to her if I see her out of respect for my husband. I just want to know am I overreacting to this or not?
