Audiences were cringing pretty bad at the Devar-Bhabhi moments & Lakshya's character was badly butchered & almost unacceptable to the audiences when he turned obsessive/negative. I guess the whole point was to make Ragini & Laksh even & show them commiting the same crimes although in varying degress & justify Laksh falling in love with Ragini later.
With Kavita's entry, they probably thought to end the earlier traingle & start the new one. Fourth angle would have made it even messier. I do agree that it was pretty badly handled & nobody gets over their obsession so soon but that's Rashmi Sharma for you, the queen of half-baked plots.
Laksh got over Swara when he promised her that he'll genuinely let her go now & try to move on fully after seeing that she's in love with Sanskaar now, to answer your question (:
