Alexandra finding it difficult to maintain long-distance affair with Marcus

London, March 7 -- 'Elephant' hitmaker Alexandra Burke, who is in relationship with America-based singer Marcus Anthony, has accepted that it is very hard to maintain a long-distance relationship as it doesn't make one feel that there is someone for you always."We're still dating exclusively but long-distance love is very hard. He's in America and I haven't seen him for a couple of months because we're both so busy. It's not easy at all, but the more you dwell on it the more it gets to you. Skype is brilliant though," said the pop star, who has been dating Marcus since last October. According to Contactmusic.com, the duo is relying on the internet video call software Skype to stay in touch. She said, "Having a long-distance relationship doesn't make you feel like you have someone who's there. They can't give you a cuddle if you want one. I wouldn't rely on him for support when I've got my team here. If I need to have a cry, I know they're there for me. Sometimes my head is all over the place".
