은데 이러다

and I'm like, but...

이러다, 이러고 and 이러면서 mean 'goes on like this', and they quote what someone said or thought. The -은데 in front is the trailing 'but' that leaves the thought half-said: 난 이거 먹고 싶은데 이러다가, 'thinking, but I want this one, and then...'. 이러다가 on its own also means 'if this carries on', which is how 이렇게 생각하실 수 있을 것 같은데 이러면 안 되고 warns against a line of thinking.
