Here is the deal, I am getting married in Puerto Rico and my best friend is planning the bachelorette party. She asked me for the guest list and I hand it over...however, I did not invite any of my fiance's sisters. They are 5 (3 of "bachelorette" age, the other 2 are pre-teens). I really do not like either of the ones that could go to the bachelorette. I have included them in the wedding ceremony (one is reading the scriptures and the lilttle one will be the flower girl) and the planning process by delegating stuff to them. Due to the fact that they have not been helpful at all, I don't feel like inviting them. Is this wrong?

Oh wow...I am sorry that I came out looking entitled or bossy. Not my intention at all! My question in reality comes from the fact that we are not very close because we don't know each other very well since they live in a different state and we don't see his family often due to school and work.
What I meant with not being helpful is for instance, that I trusted one of them with helping my in-laws get their airplane tickets (since they are a little elder) and go to get the dress for my mother in law and the flower girl. (His family leaves in a different state so it is very difficult to be there). The wedding is about 3 weeks and they have yet to get anything like that.
I haven't boss them around at all because the planning has been done primarily with my mom and my best friend so it is more of a matter of helping with my FI's side of the family. I just told them to get an orange or green dress for the flower girl. Everything else...was up to their liking. It is more of a disposition problem, that they haven't even offered to help which is kind of weird/rude coming from a Hispanic background. (Specially because I am trying really hard to include them in the whole process so that we may feel like a family.)

1 Corinthians 13:4-7
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres."
