Dear Teachers,

1. The man who dates two girls at the same time when the two girls don't know that he does so, so I will say like this,correct?

- I don't love him anymore beacause he dares catch two fishes at the same time.

Thanks very much to Teachers,

I am not familiar with this idiom, Steve, but:

I don't love him anymore, because he tries to catch two fish at the same time.

Hi MM,

I searched for this idiom and could not find it either.
In my opinion more suitable idom is: You can not have a cake and eat it
