There wasn't "pressure". But we also didn't do some dramatic bending on one knee popping open a little black box, either.
We were lying in bed one night (yes, we were shack-ups for about 5 months at that point, been "dating" for 15 months prior), and he started randomly talking about where our relationship was going... how did I see us in the future stuff. I told him the truth. I didn't see us breaking up, that I was happier with him in my life than I ever had been and didn't want that to change. So he says something along the lines of "So, should we be planning a wedding or something?"
I said, well, yeah, I guess we should do that if you want to... He said, okay. Then, we were going to sleep, and I thought hmmm... are we officially engaged now? So I asked him. And he said, I guess so.
He never actually asked me "Will you marry me?" until the morning of our wedding. And then he absolutely relished it... as he was walking out the door to go meet his family and I was getting ready to go get my hair done, he leans back into the door and says, 'Oh... since I never actually asked... Will you marry me?"
I think we both always knew. And we are very comfortable with each and not at all dramatic.
I can't say what you should do or expect. I don't know your guy's opinion about marriage. Not everyone holds it in high regard or sees it as anything more than "a piece of paper." That is not how my husband and I see it, but only you know how you and your man see it.
I will say, however, from a place of wisdom and learning the hard way, that men often do have to be "told": "This is what I want." And if you are sitting waiting for him to romance you and fulfill your desires without you asking, you will likely be disappointed. At this stage of the game (2 kids down the road) any romantic surprises should be removed from your expectations. If he were going to do that, I'd think he would have already before now.
