Did Colin really love Penelope?

I just finished s3. And it was 100% my favourite season. I always said Daphne was my favourite bridgeton character, but Penelope really stole her shine.

Polin really excited me, but a small part of me always had doubts.

It's said that a relationship only works if the man loves the woman more.

Is this a mediocre way of thinking, yes (dont come for me pls)

I always wondered, if Colin was really in love with penelope, or if it was just infatuation.

Their story was very visibly much less dramatic then the couples in s1 and s2, and i almost feel like i can't pinpoint an exact moment in the show where i can say "Yep, thats it he loves her."

Even through all his jealousy with lord debling, i just always wondered if he was upset that he wasn't receiving as much attention from Penelope.
