Is she a hoe

Im 19/m dating my gf 18/f for over 4 months now. We’ve been doing quite good so far even though we sometimes fight. I really like this girl and gave her everything i have. But its quite hard for me to accept her past. She has 4 body count and she got raped around 4 times because of her being drunk in the past. I wanna marry this girl but everytime i rmb her past, it hurts me to the bone. The fact that around 8 people had sex with her is hurting me real bad. She even got pregnant once by her ex. While me, losing my v card to her. I spent almost 2k on her so i feel like its too late for me to back down. What should i do brooo. Were getting more serious now but her past is too hard to accept.
