Will he appreciate me eventually ?

So the guy I've been seeing is really hard to be with. He has mentioned that I complain about the same things his exes complained about when it comes to how he is. He holds back a lot and I just don't know what he is thinking. He has his own way of doing things like instead of sayig yes hell say ndhskuskd and I don't know if that's what he meant. This also makes an impact during arguments. I can misread his signals or he can misread mine and we end up on bad terms. But the thing is I love him and I have given him so many chances or I've forgiven him. I haven't walked away. I feel like he does notice that because he's starting to show more that he cares but again, I could be misreading him. But regardless if he is or isn't noticing I'm giving him chances, I haven't walked away and he hasn't told me its over so does that mean he does appreciate and like that I haven't left him for his flaws and have forgiven him ? I think with his exes it was a mutual breakup not sure if they're he ones to have end it. But ya so far its still going no matter how many ups and downs we have and mostly cause of how he is. So does he or will he appreciate me ? And depending on that should I keep going too ? Or does he not care and is just keeping me around ? Cause were not official yet. His effort recently tho has been awesome ! I've never felt so wanted by him before ! It feels good.
