My male betta won't make a bubble nest!!!!! ?

He chases her and she runs for her life an she has a white dot and vertical lines but he just won't make a bubble nest. I've done a tone of research and all the babies would have home and all the conditions are right but he's too busy chasing her to breed and I seriously have done everything the breeders tell me to do! (except give them blood worms cuz my local pet stores don't have em) What do I do?
