Would a girl be sent to jail if a guy takes his life mentioning her name ?

Hi, A girl & boy initially didnt give any commitments and went into relationship mentioning the same. Howerver as time went on both got closer to eachother. In that state, both took commitment to get married. But she gave that commitment as she was afraid if the guy does something to himself. But she couldn't stay with that same false commitment so ended up opening the complete senaior and to add more she informed that she will be getting married to her ex boyfriend who love each other but then had to breakup for some reason. Girl doesnt love boy and he is not happy with that boy. Now the boy threatened he will take his life mentioning girls name. If she marries her ex. He states if you are not mine you shouldn't be with your ex. Tried to convince him but he ended up sticking to the same. Girl is guilt for what happened but she is not happy living with him. Also girl wants to inform police for his suicidal tendency/threat but at same time she is worried if that guy wont commit sucide and informing police his tendency might effect his career. She is two states ot mind regards to the same and all she want is him getting back to his normal life. Will giving complaint ruin his career, if he is not willing to take his life ?? If at all guy commits suciside mentioning girls name , will she be sent to jail?
