As
@Gj816 life changes over time. Mostly people's priorities change, some of us grow, mentally and emotionally. Some of us don't.
At some point, especially if you have kids, you find your priorities have taken a paradigm shift; some friends and the associated grab ass time with them starts to drop in prioritization. Some point in the journey you suddenly have some stupid time at some point, you test the waters, you go out and get fucked up and you wake up feeling like shit, the job is calling and the kids need a ride back from school.
Usually on that one day you realize the thirty something guy closing in on 40 something (quicker than you like), that is looking at you in the mirror has only a few years of trigger time at best, you're fucking body is a Motrin depository you realize right then that life has changed. You also see that some of the other guys that you ran the streets with are thinking they are still Peter Pan; out buying and new riding motorcycles, scuba gear, guns, weekends at Vegas and purchasing other man toys are on wife number 4 wondering why? They usually say shit like "I don't know why I can't have a stable relationship" "wow you're so lucky"? No shit really? It's called sacrifice and balance.
At some point in my thirties my mental and emotional calculus changed regarding friends and it became 1) we are not fucking, 2) you're not one of my mouths that depend on me, 3) you're not paying my bills, 4) you don't feed me or take care of me, 5) what you think of me as compared to drinking buddy a) or b) is meaningless. Most of my friends eventually had that same mental day of reckoning and even the ones that did not acquire all of the family get it, because chances are they had it, lost it and appreciate & respect how you balance your life. Most or all of them never put choices in front of you that could jeopardize your relationship because they get what makes you tick.
It may sound cold blooded, maybe ruthless; but you have to be reliable to the people who's lives your decisions impact the most, it's called responsibility. It's being a grown ass man and some men don't understand when it's time to be a grown ass man.
