Help please

Y’all seem like nice people so I need some help. I have two friends. Let’s call them A and B. A and B go to same school, that I don’t go to anymore. I want to defiantly invite friend A over tomorrow. We would be going to a party with my twin brother and our other friends(mainly his) friend A kinda gets a long with them. And friend Be does a lot. Friend A and B last time both of them slept over didn’t include me a lot. I want to see both of them, and since I saw friend A like three days ago, and slept at her house I feel like I should have someone else come over to make it seem like I don’t have just her and I am not like ‘hogging’ her in a sense. Also I just want to see Friend B. So after reading this who do you think I should invite. Friend A is a definite and friend B is either a yes or no. What should I do? I need to figure it out in about an Hour!
