Girl I met on internet acts weird, does she like me and what to do
So okay, this is a pretty big thing but I will try to summarise it down.. This girl I only met a coupla months ago on the net on a helping site (because I had a major thing in my life and I was depressed for 2 weeks) and never met in real person was well feeling really down on herself the other day and somehow hates herself. So not being the kind of guy that likes to see my friends being sad and hating themselves, I decided to see if I could help her. And I told her that she may not realise that, but people around her, including me, love her in a friendly way and would continue to love her no matter what happens and since that conversation, she has felt better. But here's the problem, she starts acting more than friendly towards me and I have noticed some weird things in her behaviour on msn that suggest that she may have a crush on me. Which is not a bad thing mind you.. but it just scares the heck out me... Here are some of the things she has been doing/saying:
1. Whenever one of us has to go somewhere or do something and has to leave msn, I say love you and she says love you more or love you too or something like that. I mean I love her in a friendly way of course but usually when I say this to girls meaning the friendly love, they would usually get the wrong idea about me and stuff but she doesn't and says she loves me MORE.
2. I have just been keeping up with compliments like saying how beauty she is and that she's smart and caring and stuff because she helped me out and I just wanted for her to know that I would love her in the friendly way and appreciate who she is. But she seems to think I'm sweet and keeps saying aww and telling me I'm a sweet guy and stuff where most girls just gets turned off by this and think I'm a stalker or something
3. This is the major thing. The day after she was feeling down, she revealed to me that she never even tells the people around her, which I assume includes her friends, about how she feels and stuff and don't open up to them easily. But somehow, she decides that I'm more trustworthy than her friends and that she felt I can be trusted enough for her to open up to me and tell me how she feels. Like she said she would never have opened up to me otherwise and that she doesn't open up easily to her friends.
Ok so my first question is for all relationship experts and people who have experienced this kind of thing. Is she having a crush on me or does she have something else in mind?
And secondly, this is for christians who can help me out here because I'm a christain and she's an atheist, I know the Bible says that it is not right for christiant to date a non believer like this, and that the non believer drives them away from God or something. So I just wanted to clarify this and also to ask for the best way to sort out this. I am asking this because I am really not a horrible person and do not actually want to tell her this because I fear that I may break her heart if she is in fact having a crush on me, esp. since she just recoverd from low self esteem the other day. So like is there a way we can maybe save this relationship or a way to end it without causing heart breaks and pain?
