All kidding aside, Lady Prudence actually did fancy Robin - outside of playing both sides against each other, she really felt attracted to him - and he to her. She was remorseful and he was heartbroken when she was led off to prison.
Dick/Robin was also smitten with Suzie (and I think she with him) and was crushed much harder than by any meteor or trash compactor when he realized she was also playing both sides with the Joker.
As he once said in his own defense "I'm not going to be young all my life". There are probably some more examples but I have to get going to work, which pays for the internet which enables my involvement in this message board. In addition to bat-love, a little cash here and there doesn't hurt either.
Farewell, farewell, I really must depart.
