Need to vent and maybe get some advice.  I have a group of single friends and about two months ago I invited my best friend who was newly single to join us when ever we get together.  She has really hit it off with this group which I thought was great.  However, I have run into some family issues and have had to cancel a few times on this group.  Basically my brother is in a situation where he is raising four kids on his own so when he needs help I do cancel my plans.  For me family comes first.  Understandly my best friends is getting fraustrated because she just doesn't understand this. 

Last night a picture shows up on facebook of the girls and of course my best friend was with them at a concert.   I am hurt because I am no longer getting invitations.  Maybe I can't complain and just have to accept this but I am angry.  I don't want her to stop hanging out with them at all, I would just like to be included instead of replaced.  I know that this sounds pretty trival but this family situation is extremely diffucult and it seems like my friends are at the point where they are just moving on, not including or supporting me.
