Divorce in Singapore

Dear sir/ madam I am an Indian citizen and Singapore PR , staying with my husband in Singapore for the past 11 years , having 2 kids . Due to family violence of my husband I and my elder son got PPO ( personal protection order ) in Singapore against my husband, after this incident he abandoned us in Singapore and went back to India . Then I cannot able to manage my suruvial with two kids while working , I went to India and left my kids with my parents during this covid period . When we were in India my husband came to Singapore and tried to sell the property in Singapore without my knowledge . This all I come to know when I came back to Singapore to continue my work . Then I filed for divorce in Singapore and summon was served to him then he agreed for mutual divorce in Singapore . Then later after two months time my husband went back to India again there he applied for restitution of conjugal right , here in Singapore we already for interim judgement for our divorce , now he Is asking for stay to stop the proceedings in Singapore and asking custody of the kids since he is also in india and stating that he cannot contribute maintenance for my kids also . My question is 1 ) he can able to apply stay order in Singapore ? This is to drag the case proceedings in Singapore I hope . 2 ) he filled kidnaping case against my father and now asking for my kids to stay with him , if this is the case how I can able to get guardianship for my parents , what is the procedure 3) he already filed for restitution of conjugal rights also How to deal with this ? Now thinking of my kids , I couldn’t able to bring kids back to Singapore since everywhere is quarantine , give me some good ideas to protect myself and my kids , and the proceedings in India what I should follow ?
