GERARD BUTLER is wary of falling in love and committing to a relationship - because it makes him feel vulnerable.

The actor has recently had to fend off a series of reports he’s dating his The Bounty co-star Jennifer Aniston.

He is adamant his reputation as a ladies man is not accurate, insisting that being single does not mean he’s a Lothario.

But he has confessed he shuns commitment - because he’s so used to being on his own.

Butler tells Britain’s OK! magazine, “I live very much in my own head and I don’t always like that somebody else is playing such a big part in your mind and your psyche. It’s tough to deal with that vulnerability because I still have that element of ‘I can’t do this! I can do this on my own! I’m all right! - and then suddenly, someone holds this power over you.

“Men are much more weak and vulnerable than they let on. I am full of phobias about commitment. Yet, when you break through those barriers, it’s great.”
