She's gone off dating me.

[Luis Fleming]

is it correct "go off" is "stop liking something"?

I'm learning English with my favorite singers song. when I was listening to Taylor Swift' song "you belong with me" , I could not understand a part of it's song. This song has lyrics like...

I have three questions regarding "go off".
1 - Can I also say She's gone off dating me? (using the gerund)
2 - Is it mainly British?
3 - What other term can I use to convey the idea of stopping liking something one used to?

It does seem to be a British expression.

Perhaps:

You've lost that lovin' feeling. Oh, it's gone, gone, gone, gone away. (From an old song.)

Perhaps:

You're just not my cup of tea anymore.

Perhaps:

They've moved on to to greener pastures.

Or:

She outgrew him.

Or:

She doesn't love me anymore.

There are others.

I've run into the term to get sick of. So, if say I got sick of eating seafood, does it necessarily mean I used to like seafood, but I ate it so much that I stopped liking it?

 

[probus]

That's exactly what it means. Coming back to your earlier question, in BrE you might say: I've eaten so much seafood I've gone off it.

That reminds me of a story. One time Shoney's had all you can eat shrimp. The first time I had several plates of shrimp. The second time I had several plates of shrimp but less shrimp than before. The third time I only had one plate of shrimp. (I still like shrimp.)
