New girlfriend is rubbish?

Anonymous
My ex started dating his old crush whom he wanted before dating me. We were together for 2 years with my ex moving to my country with me and he also joined the same university as me in my country.
I loved my ex as he was very attractive and sexy. We had an amazing sex life too. However, as time progressed when he moved with me, we started having issues and I kicked him out.

He left my country and went back to where we were previously living (he wasn't as he had already moved to my country, that's how we started dating as we were friends and I helped him in familiarizing with my country) and somehow found the same girl he had a crush on, proceeding to rekindle or this time finally develop the crush into a relationship.

My ex came for dinner with a mutual male friend and there are lots of videos of it. However, all my ex did or talk about was his now girlfriend. He was also not participating much and kept video calling her and texting her. My mutual friend also said that she is very caring and motherly towards him which he loves. He sent me many pics of together where everyone said they look like husband and wife. Whereas our friends would joke about us saying we look like siblings. He also looks at her in a way which he has never looked at me. Our friend also said that he has changed and seems much more matured and humble now. They also do everything together, from signing petitions on social causes to lunch/research work. We did these things independently except we went out a lot.

How come he's so different with her?
