Had sex now what?

As title says, i have been talking to this guy from my church for the last five months. Im f 17 he's m 21. I just turned 18 actually last week, and i know I am pretty sheltered because I grew up in a super strict church but I go to my friends church now. I also went to a Christian school without health class and I know I do not know much at all lol.

But he said he wanted to wait til I was 18 to date, which is fine. But we started kissing in December which he initiated first but I was okay with. Then I stayed the night at his house once. Then two weeks ago we had sex.. he put it in, didn't say a word the whole time. It hurt and I started crying. He comforted me and I was going to go home. But he convinced me to stay. So I stayed the night but woke up with his hand in my bra and his hand down my pants and he was awake humping himself against me. I asked him to stop and he got up and sat across the room. I wanted to go home but didn't and he didn't really say anything. So I woke up at noon, cuz we were up late. He snuck me out of his parents and dropped me off.

Saturday night I went to his house again and it happened again. But he told me to flip over, so I layed on my stomach. He told me no on my knees and stuck it in. Then no lube tried to put it in my backdoor, so I rolled over like uh what. He put it back in normally and kept saying he doesn't wanna make a mess and doesn't wanna go inside me. He took it out and told me to buy plan b and that it's not abortion but I don't have to if I don't want to. I cried and went home. Sunday morning he's preaching in the young adult class about the armor of God He ignores me all church day, then I call him that night and he says I'm too immature to date, we talk but hang up. But he was upset because he lost his job for calling off too much.

Today I called him and asked what are we then, what are his plans, etc. He got upset and was like idk idk to everything, then raised his voice and cussed and said do whatever the f I want to do he doesn't care. Said we were only friends and he's not dating me until I finish college in 3.5 years. Said we were never together and I can call it whatever I want but not that.

I talked to my friend and she made me block him and wants me to talk to our youth pastors wife, because she knows both of us well. But I still want to work it out and get married eventually because we all sin and we can fix it. Advice??
