Weddingbee boards

I have my social work degree and currently work in a treament center counseling youth. this is slight unimportant other than anyone in this line of work know the importance of boundaries and inappropriate relationships. That being said, after college I served in the Americorps VISTA program where I didn't work in direct service with teh shelter residents that I was working at. We were allowed and even encouraged to  have social relationships with the residents. I kept in contact with one of the kids from our after school program. Her mom was mentally delayed due to drug use and I would often act as her chaparone for field trips and incentive trips. I still talk to this wonderful young lady and would absolutely love for her to be my flower girl but am not sure how to ask or if it is just too complicated to go down that road. Obviously being that they are of a low socio-economic background I would foor the cost of flying them to the ceremony. I am conflicted at how to go about this or if it's just a waste of time. I just know that it would mean a lot to her to get to wear a dress and be part of my ceremony and also mean so much to me to have her as part of my bridal party. I am just too confused adn am seeking some input from anyone.

Thank you lovely brides!
