Yes.
You're wasting your time.
If you have to go on a dating website to ask complete strangers about the health of your relationship, having a seeming inability to functionally communicate with the person you're in a relationship with, then you're wasting your time in that relationship


Do you feel used?
If so, then you probably are.
If not, does it matter? You're obviously getting something out of it and it seems the guy isn't lying to you, based on the little information provided (he's not saying "yeah! Let's move in together!" and then constantly finding a million excuses not to. he's just vague about the timeline, at least that's what is in the OP).


Why do you expect, clairvoyance?
Do you believe he has the entirety of his emotional and relationship future and plans hidden in his diary, complete with venn diagrams, flow charts, and bar graphs but he's just not sharing it with you?


It means communication in the relationship sucks.


You're expecting a lot from internet strangers, aren't you?

I mean you want us to not only interpret the motives of a guy that none of us have ever met, have no relationship with, but also figure out if those are honest motives or if he has ulterior motives, based solely on what you think he said while telling us you may be misconceiving everything.

Other than that, do you know if he views "moving in together" as having the same importance as you do? Do you think he ascribes the same meaning to that as you do?

You may see moving in together as some kind of step forward.
He can just as easily see moving in together as stagnating, or trying to control the relationship, that the only next step forward is marriage.
I don't know, I don't know him.
I don't know how he sees moving in together.
Do you? It's kinda important.

If you continue this way you are indeed wasting your time. Basically you are just a convenient girlfriend and not the woman he wants to spend the rest of his life with.
Clearly a commitment and living together matters to you. Make sure that he knows this and knows that you are not going to wait forever. Get or keep your own life going, make sure you're not available at his beck and call. Not to play games, just because a high value woman has her own things going in life and isn't going to drop everything the second he wants her.

There's plenty of stuff on this by dating gurus, for free. Just check some Matthew Hussey clips on YouTube, on his site etc. And there's more ppl like him, good ones. They address this issue a lot, because it happens a lot.
Mostly what it comes down to, is that women make a man the centre of their universe. That feels needy, clingy, and not appealing. And makes you an easy target to get taken for granted. He doesn't have to do anything for you, as you're always there anyways. Always there, always available, always willing to change your schedule to suit him etc.
That's why it's important you get your own life going, go out with friends, have things you love to do etc etc.

When you change your behaviour, he could change. If he doesn't ... his loss.
Better you find out now then after you've invested even more in him.
