Josh, I understand how hard it can be to have feelings for someone when they don't feel the same way. It is great you are respecting her wish to just be friends. I've found it is best to give the other person space. Maybe she'll see more than a friend in you someday. Don't close yourself off to meeting new people while you wait though. You never know when you might meet somebody else to be your girlfriend.
I know it's hard when relationships go through changes. Perhaps she is really busy or just needs some space. Try to realize she might be at a different place.Try giving her some time, while still being there for her, and see if you can gauge her interest and what she tries to put in the relationship. Perhaps you can try to see when she's available and schedule dates when she's free. Be flexible and see how things go. Either way give it time, give it some space, and try to breathe. If you notice you grow more distant and she is too busy to take time for you, then maybe it's not meant to be. It's scary when things aren't like they were, but in the end it works out how it's supposed to, sometimes together and sometimes not. <3
This is a tricky situation. It's always confusing when there isn't any clear signs as to if they're interested or not. I think if she hasn't accepted a date, she might just enjoy your friendship. I personally never want to reject someone, so I try to let them know I'm not interested as nicely as possible. If she ignores the topic or never answers, I feel that is a pretty big sign right there. If she was interested, she would jump at the opportunity, or be excited about it. I would just wait it out and be there as a friend. Sometimes girls just need time. I feel the best relationships are when you meet someone and they become your best friend and it naturally becomes more. <3
