You have to figure out if the feeling is mutual..A crush or infatuation may be unhealthy for you.
If she feels the same way, you could have something real, but it would be an uphill battle for the both of you.
I've had a relationship that everyone felt was wrong for the both of us....The entire world was against us, so we became a world unto ourselves, and removed our feelings from society.
My location makes that possible for 95% of the time.
Eventually it became a note of defencive contention for us..It was her and I against the world, and I welcomed the confrontations..Making me a bit of an asshole at times, but the struggle became too much.
There are a few ladies right here I have some affection for, and I'm not sure if it is mutual...I'd like too think it is, and I do try to keep it in check, as I'd like too think it is harmless.
We are people....Seeking affection, and acceptance, but those two things in your case must be mutual, and must entwine with each other.
If she is playing with your feelings..Or you with hers, that is a recipe for disaster.
You are then going to have too look at yourself and your well being, and realize you are in fact standing alone, and find the strength ..to ride off into the sunset.
