Was it acceptable to ghost me?

Soo buckle up ladies because I've got some shit to recount. So I'm in university now and graduated from high school last year. I'm from a smallish coastal town. In yr 11 and 12 I had a young teacher fresh out of uni. He was smart and funny and since we were his first senior class we were all close and he basically was one of the students (but was still onto it with discipline and all that to keep us in line). I had a crush on him but of course never acted on it and he never suspected a thing. Then when I graduated we kept in contact because he wanted to hear how uni went for me trying to get into my dream course. After an email or two he sent me his phone number if I ever wanted some advice or anything. So sometimes I'd text him and let him know how things were going and that was all good. But after a few months I realized my crush was still there so my roomates suggested I just tell him and get it off my chest because what could I lose? So I texted him kinda saying small talk then I was like 'I've liked you as more than a friend for a while now, just thought I'd put it out there and see what you think.' Then he sent back asking if I was on the coast and when I said no he called me. He was really nice and the conversation was easy and we spoke about other stuff for a bit. He said I was mature and beautiful but wondered what I thought of the whole teacher student thing and I said obviously I never wanted to risk his job (didn't do anything in school) and it didn't bother me but it was something for him to consider, being in a smallish town with gossip. He agreed and was like 'yeah I'd definitely be interested in catching up for a drink or whatever and seeing.' And I said that sounded good. I mentioned my birthday coming up the following week and that I'd be back home about then and he said he'd send me a birthday text. I said thanks you don't have to do that, then we kept chatting till he wanted to go to bed so i said ok just let me know and that was that. So I leave it, and my birthday cones and goes and I think huh I thought I'd get a text but that's ok he's busy. then I came home so I sent him a text saying hey hope everything's going ok, just letting you know I'm on the coast for a few weeks if you wanted to catch up. No response. And that was about a month and a half ago. So I've been ghosted 😑 I thought he'd respect me as not just a potential partner but add a friend to at least give me an answer but apparently not. I won't text him and seem desperate. What do you ladies think?
