I would not say it that way - I would not say 'for'. Apart from that - they are fine. But I think that Americans do say it with 'for' - perhaps one of them might answer as well?

This form does exist, but let's say that it is 'non-standard'. The correct/standard English construction is 'I want you to love me'. The construction with the 'for' is heard in some, but not all, American varieties of English. I could be wrong, but it has a New York sound to me. It's basically an informal variant. I wouldn't recommend you use it, unless native speakers around you are using it too.

Everything is correct, except "for". I want you to be happy.* I want you to love me.*
