I think cv's intent to use this jealousy track to heal Raman. They have recreated the situation that Raman was faced with previously. His wife's friendship with a richer & better-looking guy (Raman's opinion) than himself. Here they will show that unlike his first wife who chose riches over him. His second wife isn't going to do the same. She is definitely going to choose Raman over Mani. If anything this is definitely going to help Raman move on with his future. He won't feel rejected any more. He won't have to spend his life with Ishita cos she wants Ruhi but because she chose him & his kids. She had an option to choose Mani. Not only is Mani richer he has 2 kids as well who could fulfill the motherhood in Ishitha. That could be the reason cvs chose to make Mani a rich eligible bachelor with 2 kids. Ishita's comparing Raman to Mani is irritating but it also serves a purpose as well. She might find Mani more polite & sweet compared to Raman. She will certainly notice the difference between sweet & bitter & decide too much sweet will get her diabetes.
