Look at your friends situation.....over the course of your friendship, was the reason for you always visiting her due to the fact that she could not afford to visit you or just not worth the effort on her part?? If it was the latter, write her off as someone to count on. If it is a financial, or other valid reason then have a heart to heart talk with her and see exactly what it is. It could be financial, it could be her man won't let her. There are many reasons why, if it financial, and it is very important that she be there, offer to pay for some or all of her expenses. However, I tend to agree with the other responses in that it seems that she is more important to you than you are to her. Having a baby, other than the added cost, should not be a factor in wether or not she comes to your wedding.
