Is this a good idea? 💑

Gah, I'm a transboy! I'm in love with a very lovely transgirl who lives in another state, and because of how bigoted her family is, I was planning to help her run away with me when we turn 18 (that way her parents can't do much about it and we'll be done with school for a bit before college). Because of my religious beliefs I honestly and truly believe she is my soulmate. I have never met anyone so similar and understanding to me in my life, yet we don't have many things in common. Just the fact that we have similar thoughts, ideas, and how well we get along, the trust we share.. Every day, we sit down and talk on kik (or Tumblr or google hangouts) about how we feel, how we sympathize or empathize about the situation, and come up with solutions. After suffering with depression and anxiety for 3 years along with an abusive relationship, this bashful young lady is a breath of fresh air and even my world. There's nothing Id love more than to spend the rest of my life with my best friend! I'm planning to propose to her before we roadtrip back to my home after we meet up in a couple years. We turn 15 this year. Does this sound like a good idea, or are there legal problems? (Yes, she's real. No catfishing 😊 and my parents know about her.)
