Gosh I remember only too well how frustrating it was when the man I loved wouldn't tell me his true feelings. He moved away to Norfolk, which wasn't the other end of the world, but he had hurt me so badly that I refused to make any effort to visit him. He was calling me all the time but I wouldn't back down. It was only through fear of getting hurt again. All I wanted was for him to either say he loved me, or drive back up to me and fetch me. He didn't do either, because he couldn't read my mind.
We got in touch a few years back and I told him all of the above and he was angry with me. Even after all those years he was still caring enough to be angry. He's unhappily married, but I'm very happily married. As we stand now, he's full of regret, and I just occasionally wonder what if. I don't want to swap husbands, because he was a real pig to me, but I'd like to know what may have become of us, He was my first love and I'll never forget him for that reason alone.
If your guy has professed love before, what's stopping him now? Is he hurt badly so he can't open up to you? You've a dilemma and a half here because he may well come around and want you in the future, but sometimes men close off for a long time after they've had a bad time in a relationship. Also, if you're in Australia and he's in the UK (?) how will you keep in touch regularly? If he has a flash of romance and suddenly wants you, can you come home or are you stuck out there for a fixed timeframe?
Excuse the wild guess here, but were you always there for him during this break up? Have you been there for him for a long time now? Is he so used to you being there that he presumes you won't leave? Is he the sort of guy who would react positively to the shock of losing you? When the Norfolk man lost me, he went out and married the wrong woman for him. He admitted that to me, I'm not second guessing.
