Thanks guys. All your advice is much appreciated.
I decided not to say it in the end, the other day we had a little row during the day, and that night I rang her up after calming down and said "we need to talk" I later found out that at that moment, she thought I was going to break up with her, when in fact, I was just going to talk about the row and sort things out, which we did.
When she admitted she thought I was going to break up with her, she said she realized how much she does feel for me, and that she got scared and sad when she thought it might be over. I've decided not to say "I love you" but I instead said that I care about her a lot too, and that I like how things are with us. I then went around and fucked her. I'll leave it up to her to say it first, and I'll say it back if I feel it
