We lived in Michigan and DH got a job offer in Oklahoma making more money, but still less money that both of our salaries combined. The same week he got the job offer I found out I was pregnant with DD#1. So, altho I hated to leave my family, I was going to have an opportunity to be a SAHM. 1 year later we were transfered to Texas (not Dallas, but Houston) and again found out I was pg. with DD#2 (I guess something about moving makes me fertile

)
Sometimes I really miss my family and am sad for them to not be close to our girls, but it really has been a good move for us, not only financially but we've had the opportunity to grow together as a family (the 4 of us). As far as being lonely, yup, I was at first. I've joined various groups and have met some people I know will be my best friends forever, no matter where we live. Your mother is right (scary, huh?), your DF will soon be your husband and then HE is your family. If you're not willing to move with him (IMHO), then maybe he isn't "the one." I would have moved to Mars with my DH, and believe me, Oklahoma was pretty close to Mars (sorry Okies

)
I would check on the cost-of-living factor. We found Houston housing to be much lower than Michigan. We bought a huge home here for the same price we sold our tiny one for there. Also, Dallas is an awesome city - beautiful, lots to do and see. The weather isn't as extreem (you'll still get season.) It is a million times better than Flint. Airfare is pretty cheap from Dallas to Detroit (less than $200 most of the time). We fly back twice a year, our families fly here usually twice, sometimes 3 times a year. We really don't have a chance to miss them much!
How 'bout taking a weekend and flying there and checking it out? You may be pleasantly surprised!
Good luck and let us know what you decide!
