How soon is too soon to say I love you?

So I’ve been dating my girlfriend for almost 2 months, and I was thinking about this the other day. In the past I feel that I’ve dropped the “L-Bomb” a little too early with previous girlfriends. It’s not that they seemed to mind, I just feel like maybe I said it before it was really true. Now, I’m all about the love, and I feel like there’s nothing wrong with expressing that. I think it’s important to in relationships, but I’m a little hesitant to say it this time. I was thinking about waiting for her to say it to me. The thought process would be that if she’s ready to say it to me, then that’s all I need to jump into it. Is it the guy’s job to say it first though? What do you guys think, wait for her to say it or say it when I feel like it?
