Being true to yourself

My biggest weakness is that I don't want to burden people. When I meet a guy I don't want to talk about what I want, what I need or what I deserve. I just live the moment as it is... and keep all the thoughts to myself, to think about them when I am alone at home.
I am terrified that talking about my feelings will destroy the moment. That the man I am trying so hard to impress will get annoyed or will be disappointed, that our relationship is not as easy breezy as he thought it was going to be...
F. is amazing. Being with him makes me realize that I really want a stable, happy relationship. Whenever we are together I take in every single moment and treasure it like the most precious of memories. But when we are apart, all these questions run around my head that I should be asking him but I can't seem to find the courage to say out loud... "Are we a couple?", "Are you still seeing your ex-girlfriend... are you still in love with her?" "Can we be happy together for real?"
Everything between me and F. feels like in a dream and I am scared that if I ask one of those questions the bubble that we have built around us will crash back down to earth and burst... and we'll wake up in cold reality. Reality is we are 800 kms apart. Reality is he has a son with a woman that is trying to win him back after having broken his heart. Reality is that I can't compete against her...
I'm pretty, I'm fun and he adores me... but is that enough against a woman that had his child, that had his heart in her hands and threw it away, a woman that lives just a few minutes away from him... a woman that managed to play with his head and made a crack in his soul.
I want to believe that if people are meant to be together in the end it all works out, but somehow I have the strange feeling that I need to talk to him about serious things in order for that to even happen... Serious things... I'm scared of burdening him, since he is already troubled enough as it is. I want to be the breath of fresh air, the place he can turn to when the whole world seems like it's against him, and I feel like if I bring my feelings into play I'll take away that "easi-ness" between us...
If circumstances would be different I don't doubt for a second that F. and me would have been perfect for each other. We think the same, feel the same, act the same and want the same things, it's spooky.
He agrees with me in all the things that need to be agreed upon for a couple to work in a long-term but he is still different enough from me, that we can complement each other.
So what should I do? Take the risk of involving feelings? There are only two outcomes... Either feelings take this relationship to a new level where I don't have to worry about who I am and what I represent... Or it can end everything... and if it does, then maybe it's good, because it wasn't meant to be... But it's terrifying and I'm just not sure I'm ready to lose someone again...
