Thank you to all, I got some good thinking points from every response.
My salary has dropped over $30K since I got here. In my 'old life', I always worked two jobs and I had a side gig that was fun and paid for some fun extras. I paid my bills on time. Here, I can't make over $47K, and that's the top pay in my field, which might sound like a lot, but my health insurance payment is huge, my student loan payment is huge (had to take out a parent plus loan for my kids college when the ex decided he wasn't going to help out), I have a car payment, my car insurance doubled in this new area, and I have huge old credit card debt from the years the ex stopped paying child support and disappeared for a year. My side gig has bombed here and I've actually lost money on that in the process trying to get it going here. The second job I usually had pays about half the money here and I'd have to spend so much time driving and on gas and tolls it starts to not be cost effective.
It's been so depressing! Add to all this frustration is the frustration of not liking the area.
Could I go back to my previous life? Probably. I've been putting out feelers and get positive feedback.
I guess what it comes down to is that I gave up A LOT to be here...secure job, friends, family, furniture. I felt like my ability to earn enough and the expenses of living in this area were somewhat misrepresented to me by my SO, not in a mean way, but in his desire to have me here he misinterpreted some crucial data.
Now, feeling like I am dependent financially on this person makes me really uncomfortable. Fact is, I don't even like what I do for a living any more, but, in the past, it paid the bills and provided insurance for me and my kids. Now, it only pays the bills, but I don't get any 'rewards' for working all day in a job I hate. And by rewards I don't necessarily mean tangible things, but, for instance, the ability to help my kids out, the ability to see friends, etc.
SOs job situation isn't necessarily that stable, and I suspect he is digging into his savings to have me here and I say that because of some statements he has let slip over the past few months. That makes me even more uncomfortable!
Well, again, thanks to all for your input, it has given me some food for thought!
