Fat experiences

Soooooo all of the dates I've had all ended badly. Part of that was me, part of that was the partners I picked. Now I'm in a place where I could make a fresh start, but I feel like I've been held back by being afraid to repeat the same mistakes.
Add in the fact that I'm a fat panromantic demisexual, and my dating pool is well... smaller.
I'm sorry for complaining, but I've tried to explain this to my real life friends and they don't get it.
Do any ladies or any size have any tips?

The most important thing is that you have plenty in common. Don't meet with someone because they are hot. There are so many pretty faces but the novelty of beauty wears thin really quickly. Meet people you really enjoy chatting to online and when you meet you'll have a great time. Worst case scenario you make a friend, best case scenario you find the perfect match!

I've been on dates with conventionally very beautiful women and its just no fun if you have nothing in common.
