My ex is w a new girl and changed?

I’m starting this off by saying I am not angry with my ex. But we dated for 2.5 years and he refused to work, lived at home, and made little to no money doing odd jobs.

found out recently he’s been with a new girl for about 2 years and now he has a good job, makes a lot of money, and has moved in w his current girlfriend and is helping to support her financially.

im happy for him. But can anyone give insight about how someone people would consider a loser does a complete 180 with a different girl.
to be honest I’m a little jealous

thank you
