The producers and writing team are desperate- what is this new Abhi getting all worked up with RB putting his wife's name on a kite? He, Abhi, is the one married to Simi and she, Simi, is in love with him not RB. RB can say and do all he wants, as Simi is not interested in him.
Watching Abhi get upset and jealous does not fit with his character or personality and really is ruining the show. I can understand Abhi's reasons for being upset with Simi but the rationale is not there for it be this instense. I feel that there were ample reasons in the past for him to display such anger such as when she humiliated him in front of her family or when she agreed to marry Nakul after getting engaged to him.
