Engagement called off

Good Day , I am neeraj singh male 28 year old ,working on ships. I met the girl in aprl 2019 and got engaged in july 2019 later i discovered during phone calls that our understranding is not matching and i was on ship far from her and only means to contact was phone. no sexual bond or any meetings i only met girl 3 times that too we fought at each time. however we have a whats app message conversations which she has saved werei said that i dont trust you and i dont want to marry you and she just kept saving messages and no reply on phone call with her mother and family they used to demand gifts and shopping for her.so i got frustrated and wrote many messages stating i dont like you and i want to break marriage. now she said she got frustrated from my messages and she is breaking the marriage, our family members sat and ended the engagement gifts were exchanged and we gave cheque for the expenses born by them and had a paper signed with cheque no and statement for exchange of gifts. now i fear they will put a case for mental harrasment and cheating on me as i dont have any messages and she has saved all my messages. while working on ship we are alone and i keep thinking about same. i fear they would file a FIR and it will effect my job. as i have to get visa to work on ship. please advise if any thing i can do.
