Credit has to be given to Krishna’s maturity

Everyone was impressed by the maturity with which Krishna handled the entire matter. Actually, when Vikram told her about the second marriage, she did not react negatively to it. Rather, she expressed the opinion that everyone has the right to love and live in their own way. Moreover Krishna Bhatt also said that after this incident there was no rift in his relationship rather her and father’s relationship is stronger than before and that is what matters most to them.

Fighting does nothing

The way Vikram Bhatt’s daughter handled the situation was perfect. When the husband and wife have separated some years ago, whether it is children or other relatives, any topic of second marriage arises. But it should be understood that nothing will be gained by fighting.

Second chance

The truth is that whether widowed, divorced or simply broken up, everyone has the right to experience love again in their life. Of course, everyone deserves a second chance in love. If he finds a partner, with whom he wants to spend his future life happily, then instead of going against him, he should be fully supported.
