Welcome to the forum~
It looks like you don't really even have a breeding set up and didn't research. A proper breeding tank would have no gravel, it would have plenty of hiding spaces for the female, there'd be no filter, etc. Unfortunately, bettas aren't like guppies, it takes a lot of work to get a proper set up and a sucessful spawn. These are fighting fish after all, so you can't just toss them together and hope for the best.
Here are some links to start you off on your research :)

some other places to look for information is in some of the spawn logs here. Breeders like Dragonlady, Mr.Vampire181, Beat2020, 1Fish2Fish, etc, have some old (and current) spawn logs that you can look through. Their set ups are all incredible examples.
While you take a while to research, have your bettas each in their own tanks (minimum size 2.5 gallons), that are heated 78-80* F, and with proper water changes. That is the basic pet set up until you have
all your research done, and supplies gathered.
