(UPDATE) Boyfriend (29m) has the ring, but it's been a while and I (26f) am starting to feel like it's never going to happen.

My original post only had a handful of comments, but I thought I should update for those who gave me advice. It also might be helpful for anyone searching the sub for this kind of post in the future.
So I did end up talking to my boyfriend that night after posting here. It was hard to bring up because, as I mentioned in the OP, I didn't want to seem pushy and he has also said before that he didn't want me to talk about it and "ruin the surprise". I asked whether he still wanted to get married, and whether there was some goal or milestone he was waiting for. At first he still didn't want to talk about it. He got briefly annoyed and said I was being impatient and it'll happen.
I explained how it's been upsetting me lately, that I didn't think I was being impatient and actually I thought it'd been too long instead. He said he didn't want to tell me his plans and ruin it. I said he did not need to tell me exactly when and where, but I need to know that this is still something he wants, and I need a timeline because I can't deal with "someday" anymore.
Finally he admitted he's been waiting for a promotion at work, because he didn't want me to have a "loser husband". (His words, I've never thought he was a loser). It turned out at this point he unofficially had the promotion and was just waiting for the paperwork to come through and finalise it. He said he had plans to do it soon. I asked what he meant by soon, because his idea of soon could be different to mine.. In the end he said it'll definitely happen by the end of summer (was spring here at the time and is summer now), so if all goes to plan we'll be engaged within a couple of months!
If you read and commented on my OP, thank you. You gave me the confidence to have the conversation and I feel heaps better. Now I can be excited and look forward to it again, instead of feeling negative and upset about it.
Tl;dr: Talked to my boyfriend. He was hesitant to give up any plans at first, but when I explained how I've been feeling and pushed a little he admitted he was waiting for a promotion at work. He recently got the promotion and promises he'll ask by the end of summer (in southern hemisphere, it is summer here now).
Edit: added info to tl;dr.
