Male Bettas are extremely territorial and will kill any other betta in his spot. There are some fish that female bettas can get along with but that requires a 10 gallon tank minimum.
If you were to continue using a small bowl/vase for a container just be sure to keep up on water changes to prevent him from dieing from ammonia spikes and try to keep the water temperature consistent (it doesn't always have to be 76-80 degrees but a temp that will not drop more than 4-6 degrees over a short period.) That is why it is important to get a heater.
As for a bubble nest, male bettas build bubble nests to mark their territory and show that they are a healthy companion to mate with.
