Marriage panicking

So… my boyfriend and I haven’t been together very long 7 months maybe 8 we never really settled on a true date so we estimate. We live an hour apart we’re both in college and we just signed a lease to live together next year life is great. We were talking about life and I asked him when he thought he wanted to propose. I only did this to get a rough estimate of what time frame would look like. He said summer. I know a couple friends that plan in proposing spring 2023 he waiting for his girl to get his degree and because we’re all friends I thought the summer of 2023 as well. He tells me no like this coming summer. I kinda freaked out a little my last relationship did not end well and I still hold on to all the problems of the past one. Is it okay for a guy to know he wants to propose so early is it normal? We’re both 20 about to turn 21 so I don’t know. In my previous relationship we were together 4 years bought a ring thought he was gonna propose and left me. am I only freaking out because of my last relationship. My boyfriend now I love dearly his whole family cherishes me heck I think they love me more. I just don’t know why I panicked like I did. I still question him about it too making sure like it wasn’t a joke idk. Someone just tell me something. I just feel like the times gonna come and I’m will be so excited and it will be ripped from me again. I know that I need to stop comparing my new relationship to my past one, but I can’t I bring it up often.
