If Raghav is sorry then why is he still married to Pakhi? If Kalpi agrees to wait for him for the next 2-5 years while he tortures Pakhi then her purity becomes blemished. No matter how incredibly foolish Kamla's character is no mother enjoys seeing her daughter's heart broken beyond repair. I actually agree with the way she dealt with Raghav in both yesterday's and today's episodes.
I also believe he has control over his emotions and stops to think. He planned a romantic proposal, hugging Pakhi, playing nice with the Kapoors, getting the marriage organized, etc. Why wasn't Kalpi in his thoughts then?
