I really feel for you, southernmiss.....i just came out a year and a half ago, leaving behind a 20 year troubled) marriage and needing to deal with 3 kids and their thoughts on the subject. My kids were 16, 18 and 20 when I met my girlfriend. I met her at work, and really had no idea what hit me, but I knew I was feeling something and the more I got to know her, the more I had to admit that I was falling in love and it just felt RIGHT......so, I left, got an apartment, got to know my girlfriend better and then we bought a place about 8 months ago....
I'm not sure if it's worse for you, living in the south, I live in CT, work and live in the same small are I grew up in, so alot of people I know still don't know about me, but a bunch of my coworkers do and my extended family does and most everyone has been great. I'm not sure how you raised your daughter to feel/think about different types of family, but I took it upon myself (because my ex was DEFINETLY not as liberated as I am) to raise my kids to not think in terms of race, color, sexuality, class, etc. I asked them to be good human beings and to love...I think that made it easier when I told them I was dating a woman, but we've still had plenty of bumps along the way.
I remember when I first started dating me ex, I kept it such a secret at work.....I finally told my coworkers about 6 months into the relationship and they were sooo happy for me, and told me I was a much happier person. I guess that's a common theme that I've heard from the people around me, even my kids told me I'm much less of a *** since I met m girl :)....but I still get paralyzed with fear sometimes when I think about running into people on the street that I've know forever, or even some of the doctors in the practice where I work wouldn't be too happy about it (although 3 of them know, and they are very cool about it....)
You have to figure out what you're own path is and then live it. Your daughter will be absolutely fine, it sounds like you are a strong willed woman who has done a great job already....my 17 year old always tells my girlfriend and I that he is a much happier kid since living with the two of us in an unconditional love household...that makes me feel good.
I have no idea if I helped or not, and I'd be happy to talk to you about whatever, whenever you feel like it. Hang in there, girl.
