Kit Harington finds relationships difficult.

The 'Game of Thrones' star - who has previously been romantically linked to Rose Leslie who plays Ygritte in the HBO series - revealed he is currently single and finds it challenging sustaining a healthy relationship as an actor.

He said: ''I'll never talk about any particular relationship I've been in. But I will say I'm single at the moment.''

Kit - who plays Jon Snow in the fantasy drama - explained the nature of working in the television and film industry means he is away from his London home for much of the year which means it would be tough to keep a fledgling relationship alive.

The 27-year-old hunk elaborated: ''Relationships as an actor are incredibly difficult. With someone who's not an actor, because they never get to see you; and with someone who is an actor, because you're ships in the night a lot of the time.''

The 'Pompeii' actor went on to say he would have to sacrifice either his relationship or his career if he was trying to juggle both, because it would not be possible to balance the two unless his suitor wanted to follow him wherever he went.

He added: ''I mean, ideally, if you keep acting in the film world, you're a travelling salesman. And your options are: sacrifice a lot of your career, to make sure it's not unfair on the other person, or find someone who is willing to be your travelling circus. That's where I stand, and I'm trying to address it at the moment.''

Despite his struggle to maintain a healthy love-life, Kit admitted he is content with his life and is not necessarily searching for a potential partner.

Speaking in the January issue of British GQ magazine, he added: ''I'm happy. I'm in a comfortable place. But I have to actively remember to recognise that a lot of the time.''
