Op, ignore the suggestions from some posters that you shouldn't go to see him this weekend. The very issue in your relationship is lack of communication and knowledge of where exactly each of you wants this relationship to go.
Reality is that for some people, a relationship where you see each other at weekends and have your own space during the week is something which works for them, and if that's what they want, then there's nothing wrong with that. Similarly though for others like yourself, there comes a point in the relationship where you want things to move forward to a point where you are say, living together. But neither of you can possibly know what kind of relationship this is if you're not prepared to talk about it.
Being afraid of opening up says to me that you don't communicate about things which are really important, and tbh if you want a future together you need to be able to do that, because when things get tough, such as facing illness, family bereavement, money issues, etc, if you cannot communicate then the relationship will not survive the difficult times.
Talk to him honestly. Tell him that you've reached a point where you're missing him more and more during the week and you want to talk about where you're going as a couple. The fact that he's looking for work currently is possibly the perfect time for starting to think about whether he might want to look for work closer to where you are, with a view to moving in together in the near future.
From his point of view, he may not feel he wants to commit to someone who cannot open up to him after two years together. And because you don't open up, he can't read where you want this to go, and he's not psychic.
If after talking to him it turns out that you want different things, then you can re-evaluate what you want to do, and whether you want to remain in this relationship. But you can't make a decision if you don't know how he feels.
Also, if after this discussion it transpires you're on different pages, then that has nothing to do with the fact you've opened up, it just means that you've opened the communication channels to discover where you're both at.
And ask him why he didn't come to see you when he said he would. If you don't ask, then you can't possibly know what he's thinking. But don't play games as suggested above.
