Friend advice please help?

I think you have a right to feel the way you feel. You feel that she hasnt given you enough attention. It's always good to rise above one's feelings of insecurity and if you want to go, just go. It will give you a opportunity to see if you still enjoy being with her. This happens a lot when someone gets a boy friend so you are not alone. It has been a learning experience for you since now you know you cannot depend on her. But for just seeing her on the weekend, its not a big deal so if you have nothing else to do, go for it. Just dont get your hopes up that she is going to return to the way it was 7 and a half months ago.
