I am the daughter of the bride and MOH. I haven't   had a dinner with my mom's f.i. yet. I haven't met his grown children yet either. Should I  host a small engagement party with cake and punch? I'm not sure if it's my place to host and I'm not sure if I should initiate  the introducing of the families.  I also want to wait for both the  divorces to be finalized before I host or plan anything wedding related.  Yes, they are both still married to other people but divorces will be finalized this month.
