I need justice,I don't want to get cheated .

I'm a divorcee. during my divorce I found one person in a matrimonial site and we got along well and he promised to marry me and so I accepted for physical relationship.. during my divorce time and inspite of having physical relationship he was still looking for other profiles..when I caught him n fought he stopped.and somehow I got in touch with his dad n explained everything n he supported me and they stopped finding gals for him.. later we started staying together in and off. During lockdown one month we stayed together and due to small fight..he somehow managed to send me to my house and he blocked me everywhr and he went to PG leaving his own house.N I told his family and they all told me they will support me if he refuses to marry me..but now they all r silent.n mean while wen my friend tried to convince him after two months this man spoke negative abt me. Saying she came to me for sex and sh was not physically happy with her hubby and many more he has spoken..I gave him time to accept the truth..he didn't . but mean whil he I was completed depressed and had extreme health issues.. n I have filed a case against him. And now he has reached my sister and brother-in-law and he has spoken all negative abt me in a very bad way to him also. Again after knowing that I'm depressed n sick.. though this man had many drawbacks I didn't tell anyone anything and he is a good man n I m saying the same .I want to forgive him n I want him bk in my life..if he doesn't want to marry me than for sure he deserves to be punished for cheating me and for talking against my character.. He has made me to leave my house and he has left me middle of the road now...what can I do now?
