It's important to most men that they can play house and pretend everything is going kumbaja in their house . While we all know that's not how it works.
the worst part to refer to my first paragraph, is the fact men don't talk about their problems. So even if you're "new forced homie" has relationship problems he won't talk about it. While women...they'll spit that shyte without hesitation wether it's about the dead bedroom or your bad behaviour...
Most married men are good at not sharing problems with their male friends, especially their unmarried male friends. They have a better chance of telling a fellow married man that things aren't going well. These men are good at not letting the outside world see their problems because married men have a smaller connection to the outside world.
Men in longer term unmarried relationships do this to a lesser extent. This problem of men isolating from their friends gets worse as a relationship gets worse.
Men in relationships (especially marriages) have a terrible habit of letting women dictate how they spend their time and how often they socialize with other male friends. For men who live with girlfriends and also married men, it's easier to justify seeing other couples because there can be dual couple hangouts.
There's an extreme example of this in my primary social circle. When I want to spend time with one of my male friends now, he has to ask his wife if he can spend time with me. He can't play tennis with me without checking with his wife. It's ridiculous. Now, he's often citing some child related activity like a child's birthday party as a reason why he can't play tennis with me or do some other social activity with me. When he was a childless married man, he was also claiming that he had to check with his wife to socialize with me.
I have told this story to some of our mutual friends who are also married men. The other married men think his behavior is ridiculous. The other married men try to justify his behavior but even they can't do it. If other married men think the behavior is bad, then it must be quite bad.
This particular married man is a man who was able to put up a triple digit notch count before marriage. Once he got deeper into his current relationship, he got more isolated from me. He didn't started pulling the "check with his wife crap" until he was childless married. His crap has gotten worse since his child was born.
As far as my other local area married friends, I notice that they are not very responsive to invitations to socialize in real life. They might be somewhat responsive to text messages (and occasionally phone calls) but not responsive with real life socialization. The ones with children will cite child activities at times too but never text me a "check with the wife" statement or say it out loud, even if they are doing it. I have some other childless married friends, but we don't see each other in person that often. They are able to randomly invite me to social functions. Even with them, I don't propose social functions too much because when I do, it often won't happen.
Since a few of my local acquaintances got married, I started seeing them less often too. It got even worse when those acquaintances had children.
It is more difficult for unattached men or men who have shorter relationships to have consistent male friends with married men or men in more serious unmarried LTRs.
