Recently i just started with a girl and i really feel for her but yet im still scare.. We just know each other less than a month and we started 2days ago.. She was asking if she could come to my house overnight. i agreed with that but on that time i wasnt get ready and didnt plan anything untill she hug me at midnight and suddenly she's started trying to make it with me.. But im really scare on that time because its been so long i stopped it since broke up with my exgf last time.. and the problem is i dont have the safety thing on that night and i refused to make it and she angry me untill today.. i smsed her but she only reply me "I'm busy". What does this mean..? she want break up with me just because i dont want to make it?

In case this happen next time without the safety thing, after make it. got anything to prevent she from pregnant?
