Honestly, I think your ego is the same as your friend's. I always play with friends, it's normal for someone to get angry there at the time of a game because they lost due to a bad move or bad luck, but then it always goes back to normal and it's just pranks between friends. I think it's unnecessary for you to come here in a community and expose this, and be bragging about victories over your friend, that's normal in the game. Resolve this internally among friends, not in a community. It's just my opinion about it, you have the right to post whatever you want here. However, here is my opinion, if I add it to you, great. If you think your attitude is good, that's fine too. We are different people and we have no obligation to agree with everything or have similar thoughts, but I leave my advice here, and I respect what you think is right.
