Insensitive Boyfriend

So I was having a horrible day yesterday due to my living situation and family and I didn't really have anyone else to turn to but my boyfriend. I asked if he would pick me up and we could go anywhere or do anything I'd even pay gas money. I just needed out of the house. He said yes and came and I started talking to him about it in the car. I was talking about how sad I was, what a shitty day I had and crying, basically just needing to be comforted. I hate seeming like that girlfriend but I was just having an overwhelming day. He comforted me a bit and hugged me then moved onto different subjects, which is fine. We looked around some stores and messed around and he bought me food and I decided he should take me home because it was late and he was exhausted from work and I thought he needed rest. He said okay, and I started talking about stuff, venting some more and since I'm a sensitive fuck, cried again. We changed the subject then less than a mile away from my house, he pulled over into some dark driveway and started kissing me. I thought okay, this is fine. Just getting a kiss in before we end up in front of my house. Then he leaned back and asked me to suck him off. I felt extremely uncomfortable because it was in a public area and I was just crying not ten minutes before and the whole trip was me just needing him to be my best friend and comfort me. I tried to do it but it felt wrong with the circumstances of the night and I stopped and asked if I could go home. He apologized and the car ride was silent until he dropped me off, and drove away before even checking if I got inside. We texted a little after and he seems angry at me because he felt he did something wrong I guess and today, the next morning, he's not talking to me.
