I'm new to this site and hoping to understand more about Christianity. I was taught some about Christianity in my younger years and try to leverage that to understand more about Christianity sometimes, but sometimes it leaves gaping holes in my knowledge and understanding. I think this may be one of those instances. I may be incorporating some misunderstandings from what I've heard so hopefully you can forgive me if I misspeak.
While talking with one of my friends about her future as a Christian, eventually the topic turned to her future family. She explained that since she was little she had always dreamed of falling in love and getting married to essentially prince charming. I feel like this is a pretty common dream among young girls. As her thoughts poured out though, she continued to share that perhaps that wasn't a possibility. Not only might it not happen like in a fairytale, but there were more complications. What if she fell in love with somebody who wasn't a Christian? What if she fell in love with somebody that wasn't going to live where God called her to live? I could go on, but you can imagine the flavor of these suppositions.
This made me really sad. I'd like to see my friend happy. That didn't seem to align with my understanding of a Christian God. My question is hard to ask, but I guess. Is that a possibility? She can't be the first person to ever face this, in fact I would bet it's frequent. So is it possible that God would ask his followers to walk away from love in interest of his plan? I understand it could be swept under as that "not really being love", but if that's going to be the answer, I don't think I can just settle for only that. I would hope for at least some context of why things had to be that way.
I realize that me disliking something doesn't change whether or not it's correct from a Christian standpoint, but I've found that understanding and learning more can help with these situations. I know you may not be able to give me a full answer, but I have no idea where to even begin looking for answers to this. I'm also not just asking for an answer to this without any work, but this is important to me and I feel completely lost.
So I guess to sum it all up:
are followers of Christianity allowed to love whomever they choose?
If not, are they called by God to leave those that they love?
EDIT
While I feel those are my questions I want answered, I see they are strongly opinion and interpretation driven (potentially). With that in mind, I guess I would redone my question to this:
I believe that people have likely struggled with the choices associated with love. What scripture (or other helpful insight) can I reference for guidance in answering these questions?
Thanks in advance, I really look forward to finding answers.
