Is it possible for two characters to fall in love in two months?

I'm nearing the 320th page of my novel and about two months have gone by since the characters first met each other. Now, they've been through a lot together in the past 300 pages and now that I'm nearing the climax, they are going to war alongside Lycans against a race that I invented myself (Since I got tired of cliche vamp vs wolf stories), and I'm just wondering about the last time they talk to each other, would it be right for them to finally declare love for each other? They've been dating for about a month now, more or less, but love is an entirely different thing. Considering all the battles they've fought beforehand, I would ume that emotions are intensified under pressure but still, would it be realistic?
