Did it start back in season 1?

It may not be a resolution but it is some character development. He has accepted that April may not like him and is giving her space. To me it was like what was happening with Leo's leg. We saw his leg getting better bit by bit and after Vision Quest he was better. At the end of 'A Foot too Big' it seems like Donnie is starting to accept that she doesn't have feelings for him. In Vision Quest Leo tells him that he needs to leave his worries and fears behind when Donnie's concerned about leaving April and Casey alone. After Vision Quest we see Donnie not being concerned about April the whole time and gives her space to make up her own mind. Yes the crush was subtly there in Meet Mondo Gecko but he didn't say anything to Jason or April.

Anyway what I don't understand is the fact that everyone was complaining about Donnie being obsessive and the whole romance plot but now that it's subtly in the background and he isn't being obsessive, people are still complaining.

Since season 1 Raph is a lot calmer and in control of emotions. Yes he seemed to be suddenly angry for no reason in Clash of the Mutanimals but anger is in his character. He has learned to control it better but he can still lose control sometimes. Someone with anger issues can't always remain calm. He was probably frustrated by the lack of progress.

We've seen Mikey be able to be in command and take control. He also isn't been shown to be an idiot but instead tends to have more disgusting jokes. His brothers don't seem to look down on him anymore and take him seriously.
