It’s hard to comment on this, because every relationship is different, but if you have a bad feeling, my advice is to trust it. You can devote more time to changing your behavior, try to catch yourself before you tell him what to do and offer support instead. He’s dealing with a lot and it’s probably very hard for him. But if he’s not mature enough for you to feel comfortable with the relationship, then maybe now is just not the right time. That was a hard lesson learned for me, to realize that just because you love someone doesn’t mean the relationship will work out. Wanting him to be a different person is going to be very frustrating for you, because you can only help so much and people don’t change overnight. Not that he shouldn’t work on his flaws, because blaming other people and things for his problems is not going to help him. My ex had similar complaints about me, that I wasn’t mature enough and too dependent on him. Even though I’m still working through that loss, I learned a lot of things that I would have continued to be oblivious about if he hadn’t ended it. In fact, now that it’s over, I wish I had had the courage to end it first.

This is just my opinion based on my experience. He is hurting and maybe staying with him is a better choice for you both, a chance to support him while he improves and giving him support while he grows. But you should do whatever feels right to you. Good luck to you, you will figure it out.
