I definitely think you need to tell him what you want. If you want to be a stay at home mom/wife, tell him. You have to make it clear what you what out the relationship and out of a marriage. For example, I am the total opposite of you. I hate staying home and cooking and cleaning. I'm a terrible cook lol. So before I got married, I made sure that I made it very clear to my then boyfriend that I wasn't going to change just because we were getting married. That way, he knew what he was getting into. I told him exactly who I was and what I did and didn't want out of marriage. So you just need to let him know.
Maybe he won't like it, I don't know.
But I actually think that most men want a wife that is willing to stay at home, because most women now don't want that anymore, unlike the old days. Most men (not all) want a wife that will cook for them and just love them. Seriously I know this because some guys don't like that about me.. which is why I ended up with my husband. lol..
But if he doesn't like it and it doesn't work out.. don't worry about it because even though at first it will be difficult, you'll get over it. And one day, you'll find someone who will appreciate you for you who you are and what you want out of life. You deserve to have someone who wants the same things as you do in a marriage or relationship.
He might be that person.. but you'll never know it unless you talk to him. =D
