He can do raasleela with 4 women who are his wives but he has the audacity to insult Chitraganda and abandon her even on doubt of her cheating on him. Even if she actually cheated on him he should be the last person to point it out as he too had 3 wives apart from her. Now some will say it was different era and it was common. Yes it was but jo galat hai vo hai. Yes Draupadi had 5 husbands but she was insulted and even called vaishya for it. Also she had terms and conditions for it like every year she would spend with only 1 husband and before shifting to another husband next year she had do some purification process to retain her virignity. Did Arjun too had these terms and conditions? No. What he did to Chitrangada was so bad. But she brought it on herself. Who told her to marry a twice married man?(Subhadra was 4th) She had a better life as a boy being warrior and protecting her kingdom like any son would do. But after marrying, her life changed for worst.
