This is a toughie, a lot harder than it seems.
Ok I'm going to split my response into two completely different answers, the romantic and the realist. You can then decide which is best.
The Romantic in me would say that Love is a glorious thing you should deffinately tell her and sing it from the rooftops too. If you're sure that you do have strong feelings for her then why not tell her.
However the bitter Realist in me would remind you that you've only been going out for 2 months and that love and lust are often mistaken for one another. Why not see how things pan out? And the even more bitter realist in me would also tell you that relationships are all about balance, you're a team, and that means that you should tackle big obstacles together. Now if you tell her that you Love her it totally breaks up this balance, what if she doesn't love you back? What if one of you sees this relationship a lot different to how the other sees it?
So in answer to your original topic and to summarise what a few different people have been saying, NO Love isn't a problem but in my opinion it is a big hurdle every serious relationship has to cross and many people trip over this hurdle and end up face down in the mud with the illusions of how great their relationship was shattered around them. Maybe you should use a little bit of tact, or wait and see how she feels. Or just blurt it out...
Good Luck anyway.
