Ex's new GF

So I bumped into my ex who I dated for nearly 2 years the other day and he was with this girl, he called me tonight to pinch a fag as I only live across the road and invited me up, which I think is a good step in the right direction to where we wanna be as friends and I met his new girlfriend! She's super cute and really lovely and I'm just super happy for him genuinely glad he's happy! 
Am I the only one who has felt like this? He's a good guy but we just fell apart and I'm so happy to see him happy is that weird? 
Cute wholesome little rant here 😇
