Firslty, Mam, I advice you to not to take any wrong step in your life as your parents will not be able live their life if anything gets happen to you.
Secondly, I really appreciate the thinking that you have with regard to be with guy with whom you get intimated for the first time in your life.
Thirdly, but, it’s not your fault that you met wit a wrong guy who may not deserve your love for him.
Fourhtly, yes you can file a criminal complain for sexually assaulting you on the fake promise of marriage as It amounts to rape.
Fifthly, once you file this, he would be in trouble, and lesson for others to not to repeat the same with any girl ever in their life.
God Bless You, and I ll pray that you may get the best one for you very soon in future.
