Here is my take:
He is super mad at her for both Inder's death and Baby's miscarriage. He considers he lost 2 ppl due to her. His anger is 1000% justified regarding this in my opinion...She is the reason for the death of both of them ( She lead Inder to death and lost her baby due to her carelessness, Impulsiveness, foolishness and wrong priorities..She was so unreasonable that Inder could not have stopped her even if he tried to and as a pregnant woman, she should have prioritized her unborn baby over anything else). I know ppl here won't like my opinion but this is what I feel regarding this.
But he claimed to unconditionally love her still told her to leave without trying to understand her pain and that she is devastated too..He abandoned her without any minimal concern for her- even for her safety /well being..Like jeeye ya mare , koi farak nahi padta..I hoped he wil come to some sense after the initial shock...But no...What he did is equally wrong to what she did IMO (I so wished atleast they show a scene that he was concerned about her when she disappeared...and knows now that she is safe...Now I have lost hope for such a scene since instead of showing such a scene, they are destroying him further by making him say he never considered her as family...which I think is not true..he is saying this in bitterness, thats all)..
Instead of balancing the characters so that they can be brought to a common ground, the makers are degrading one character further and further so that they can over justify the other character ( they don't have the guts to make her move on without over justification)...
Now after all this , how are they gonna bring them together ? Will it be just a compromise for the kid after the custody battle? If anyone wishes for a Sahan reunion after all that makers are doing to the characters, its insane...That is why most of us are like let them be separate...
Who knows , thats where they might be heading...if the follow the show they copied from, Dilba is the end game..I heard the kid dies in that show..Is that true? If yes, I don't want that part...I HATE it when they kill off kids...
