Hi and welcome.
Sure, advice I can do. I assume I am quite a bit older than you, and come from a different life point of view.
So here's my advice... neither of you are ready for a relationship. You have to work on you and he has to work on him. The relationship you currently have with each other sounds unstable at best. Sure, you can try to stay in a relationship with him but what will happen is more of the same. He is not stable (yet) and you are not stable (yet). Both of you will continue to bump up against hard places and triggers and react to one another reacting to one another. The moment of fun and true connection in there are lost in amongst all the hard and unfathomable bits.
So here's my advice: take time out to work on you. let him take time out to work on him. Relationships aren't supposed to be like this.
