Lavender Brown and Hermione Granger.
Hermione Granger was the first girl Ron ever liked (as more than a friend). However, he was attracted to Madam Rosmerta, asked out Fleur Delacour, and dated Lavender Brown - all before his relationship with Hermione went beyond friendship. He also went to the Yule Ball with Padma Patil, but he had no interest in her, even though Padma & her identical twin sister, Parvati, were the best-looking girls in the year. It became clear that Ron had romantic feelings for Hermione in year 3, when they were thirteen.
Ron Weasley loved Hermione. Harry only loved her like a sister.
The books suggest that Ron never really loved Lavender Brown, but instead loved Hermione.
I wouldn't say that they both started liking each other at the same time 'cause that kind of impossible so i think Ron started liking Hermione first 'cause in the 1-3 book Ron irritated Hermione a lot and was jealous about Hermione crush on Lockhart.But in the Yule dance in the 4th book when Ron got really really jealous of Krum then after that all the jealously started happening between them.I don't remember much from the 5th book but in the 6th with Lavender and Ron together , Hermione was very jealous and then in he 7th you could tell they both really started falling for each other.
