What do I do?

Okay so a few days ago I went with this guy he said he wanted to tell me something. My grandfather just passed away and my father had to stay in Mexico(with his mother since his father passed) My mom has 3 other kids and has back problems. In May my mother and I had to stay in a shelter due to my dads escalated behavior. I bought a car and hit a deer a week later the insurance totaled it even though it was drivable. I withdrew the claim and paid $2000 to fix it even though they claimed it was $9000. Soon after the engine started to go out. I feel overwhelmed going back to the guy. We had hooked up 2 times before this happened. I had told him about everything that was happening I felt so frustrated. I felt like I had no one to talk about anything. My boyfriend was in jail and the jail he is in is about 2 hours away. Anyways I turned to this guy I don’t know why if it was for distraction i don’t know. He sent my a message saying he wanted to tell me something I foolishly listened. I went into his car and he drove around a few times. Before he parked. He leaned in and began to kiss me/my neck. I told him to stop. He said why and I said I didn’t want to. He continued to move forward. He put his body on top of mine. I moved so much to try and get him off and he would put on more weight. I wiggled out of the passenger seat into the back and he followed. He began to take off my underwear/bottoms and I said no stop and tried to pull my bottoms up and he didn’t stop. I was laying sideways and then he just did it. I was still moving and wiggling around but he was too heavy for me i tried so hard. I even opened the door but no one was there and he just closed it and continued. He then asked if I wanted to go into his room and I told him no and to take me home. He took me home and didn’t talk to him. I didn’t want anyone to know I just felt like I don’t know what to do this would be another thing in my life. My grandfather left I don’t know when I’ll see my father and my mother has enough problems. The next day my boyfriend was out of jail and it came out because I would move too much when we were trying to have sex. Like I kept stopping him and when he could try to kiss my neck. I didn’t react well. It came out and now he doesn’t believe me. I’m so scared to go to the police because im afraid they won’t believe me, but my boyfriend doesn’t believe me. I just ugh I can’t I can’t I’m sorry what do I do
