Need Advice

Hello guys, I’ve been engaged for around 9 months (arranged marriage) Alhamdulillah have established a great relationship with my future wife. We were supposed to get married this month but a first cousin of mine passed away last week, first death in the family we’ve decided to postpone the wedding. My fiances birthday is coming up this week, I’m confused as to what to do, I can take both our families out for dinner, don’t think meeting alone will be an option. Would appreciate advice as to what and where I should do. Thank you!
