Dear Sonalika:
Because you have major life plans in regard to this man, better get all the details possible so to decide whether he is trustworthy or not. Therefore I ask, when “that girl started messaging him desperately” do you know what it is she messaged him, what were her words?
How often did she message him, and what did he tell you about her “messaging him desperately”, how did it explain it to you?
