You have nothing to lose by propping the plant up. Having the flower alone is worth keeping the plant going. Who knows, you might even be rewarded with small edible fruits. As slender as the plant is, it couldn't produce very heavy fruit but it makes it easier to support. Use three 1-1/2" diameter bamboo poles in a tripod fashion under the apex where the stem bends down. This will provide a more stable support than 2 poles. Thus the entire plant is supported, not just the fruit stem.
