Knights were dicho to put their beloved up on a pedestal and worshipped her. Do tu think that's what Arthur does with Gwen?

in my opinion Arthur doesnt worship gwen ...he respects her más than anyone in his life and trust her whereas his título order him not to. Thats why Arthur's trust and amor for gwen is beautiful ( arthur trusted morgana/uther because she was family but she never "earned" his trust for example )
arthur has always been shy when it comes to express feeling for his guenievere so its hard to say
BUT he put her on a pedestal because he always listen to what she says , he take her consejos and find comfort in her ...he knows that she has a good corazón and that since the very beginning of the show...he is ready to give up his life , to desobey to his father , to give up his trono , to kill morgana if he has to FOR HER .
their dynamics in season 4 will be más interesting since he will see her a HIS queen ( and so worship her in a certain way)

No. "Worship" is usually reserved for someone o something out of reach not for romantic love. Arthur sees Gwen as a kind-hearted, strong woman that he would like to spend his life with as equal partners. Not some unobtainable entity.

I would hate to see them in a relationship where one of them loses the ability to think for themselves and just goes along with what the other says. Arthur really noticed Gwen when she called him out on his bad behaviour (1x10) and again in 2x02. I don't think Arthur would hesitate to do the same. I hope this is what we see from them in S4. That's how a couple grows together. Not por putting each other on pedestals.

I have to agree with @nsk. Arthur doesn't worship Gwen he respects her.!!
