Why did my ex totally change after break up?

When we were together, he was broke and also very proud, it meant he wanted to pay for everything but couldn’t afford. So I wasn’t wishing for too much, I was working mostly and we spent evenings together curled up in bed, watching movies, playing games, working together, going to cinema, going on dinners, walking around and so on, he had some ideas, but I didn’t have time he didn’t have money. So we waited for better times to do them.

It’s been 9 months since break up, he got a much better job before break up, he can now afford his hobbies, he got a bike, he goes climbing mountains and hiking every week, he also likes mountain biking, he was a sportsman and was really into gym and was a handball champion but I never expected him to be so outdoorsy. What caused these changes?

He’s like 180 percent different than what he used to be.
