My heart aches for you! I know many who always complained but never put themselves out for others. They always thought everyone else should be perfect and cater to them. Very sad.
We were never asked to host a gathering (party) but we tried to start a tradition at our congregation. We would invite the friends over, everyone bring a passing dish, and we would supply many other items. It usually cost us about $200.00. That is ALOT for a small family with babies and many financial pressures. It was a lot of hard work, but there was never any time to socialize and we felt a real need to try. We wanted a little traditional thing for our kids to look forward to every year, seeing how they couldn't look forward to christmas, birthdays, etc.
The first time I don't think any elders but one showed up. There was a fantasy football game they were playing. The next year, after much planning and organizing, the circuit overseer had called a meeting for all the elders in the circuit on short notice. So no elders again until after the meeting 2 showed up for about an hour.
We did this for 3 years. I think I only recieved 2 thank you notes and one was from my mother. We were NEVER invited to anyone's house for dinner or anything. We really tried to reach out but mostly got burned. Sorry you had it worse, I feel so bad you had to supply all the food and lose your items from your freezer. It breaks my heart. You and your husband did a good deed and tried your best. You can be proud of yourselves that you did, any other group would have taken up a donation to cover the expenses and not trample upon your hospitality.
