My step son is really irritating me lately

I’m experiencing a lot of negative emotions towards my step son and we have even discussed it with my husband.

I think he can be arrogant and is hard work and I don’t really want to deal with it. I then feel guilty, but it’s like I can’t help but be annoyed at him! I am almost 32 and he will be 14. He sometimes behaves like he knows it all and I don’t like it when someone isn’t humble, kind etc.

It is just hard to accept that I have to keep living with him for many more years. I do have many good moments with him, but lately it has been more challenging for me. What can I do? What teaching/concept can I go through? Thank you.
