Seriously, what does fateh think... he is jealous of tejo and angad for what?? when he betrayed tejo with her own sister and backstabbed her, introduced jasmine as his wife to everybody and also in public occasions , he went to the extent of asking her to give him divorce and get out of the house because he thought that because of tejo, jasmine was being shown down by his family.
He dint feel guilty then .. but is feeling guilty now I mean why??? and that why is he feeling jealous... he claims to love jasmine right then he should be happy he is marrying her, he knew from the very beginning that his family will never support his marriage with jasmine.. and now both jasmine and fateh want family to support them. Do they even realize the grave mistake they have committed (I don't think so).
Tejo on the other hand is making it clear that she wont come in between fateh and jasmine, and neither would spoil jasmines life, fateh has no way out but to marry jasmine now, and like KSV is thinking even if fateh crosses the line and stops tejo's wedding .... Tejo would never take him back her wounds are very raw and deep.
