Well, it looks like the person who posted that just feel insecure and feel envy of his friend, its normal especially if his friend is actually winning more than he do, and it will be more extreme if that friend is actually flexing to him, maybe thr intention of the friend is not to brag or anything, its just that the one who posted is taking in wrongly and feeling that way because of the frustration when it comes to gambling, I think in his mind he is questioning why his friend is getting a win while he is not, I think the poster should talk to his friend, or be distance if he want to stay friend with his friend, because for sure there will be a point that their relationship might be affected because one is being envy and insecure. That will not be a healthy relationship between friends anymore.
