Should I go?

I have a really tough decision to make. I'll start a little from the beginning. I had a very abusive husband. He had beat me almost killed me. Choked me out. Ran over my leg with his guy. He allowed his friends to hold me down and all 5 of them took advantage of me... It took me 9 years to get out of that relationship.....

I ended up making a friend who was gay. She helped me through my divorce and was there through everything. I ended up getting the house in the divorce. My ex husband got mad and came over there while we were both over there and was banging on the door. She carries so she pulled a gun on him and I called the police. I then got a restraining order. I caught myself catching feelings for her... I didn't understand and I was confused. You would think a women my age would have her sexuality figured out, but I guess I didn't. I ended up telling her how I felt but said I just wanted to be friends... That didn't last.. We quickly became more and I've now been with her for 3 years.

Well... months ago her dad died and she wants to go back home to Wyoming to help her mom. Shes planning on buying a ranch down there to live. I was worried how a long distanced relationship would work, but I knew this is what she needed to do.

Friday she took me to the park and said she wanted to ask me something. She wants me to go to Wyoming with her.... As her wife... She proposed to me... and she's fine with me having time to think.

I love her more than anything... I'm just scared... What if the marriage is to trap me and i get abused again... She has never been abusive towards me ever, but I just couldn't help it crossing mymind. I've also always lived in city. Living on a ranch would be new. However in the city here there's no one here for me besides her. Once she leaves its not like I'll have anyone here. I love her.... Its just.. I spent 9 years with the most horrible person ever! These past 3 have been the best years of my life. What if marrying her and moving jinxs everything.... What if I wasn't meant to have that big happy ever after and what I have now is as good as I'm supposed to get and pushing it ruins everything.... Plz help..
