cmjk - video-games was an example. That was just one example. He is totally and utterly focused on her. That's all fine and good, but there have been numerous times where he has totally ignored myself and other mates (footy trip is most recent) to focus on a women who gives him no where near as much attention as he gives her. And FYI, it's not like she doesn't know my sister and needs comforting. Believe me, gaming does not dominate my life. And yes, I am sad that I've practically lost a mate.
The reason I've brought this up is because I compare him to another mate who has been engaged for 2 years but hasn't changed at all, and my cousin who got married last December and still makes time for his friends. I guess you don't understand that this guy has totally done a 180 since getting married.
I don't know why kind of friends you have, but a majority of my friends in relationships, both male and female, hardly change.
