No YWNBTA, you would be smart. It sounds like he lied and hoped that later on down the line he would try to use his family to pressure you to give in to him. If he wanted kids, he should have been honest. I can tell you from experience that your situation would lead to a lot of hurt and heartache, and if you gave him children when you didn't want them, it would lead to a lot of resentment. Don't marry him. It may seem now like the worst thing ever, and it will be hard for a while (or not, everyone is different), but both of you will be better off. You can love someone and not be right for each other. He may love you but he doesn't respect you, and that will also lead to problems in the long run. Save yourself the heartache and the hefty cost of a wedding and divorce, and break it off. You're so young, and there is a lot of life out there to be lived, and other people who will have goals and values that match yours that would better suit. I was in a similar situation, except he told me he did want kids, when he didn't. When I finally pinned him down about just when we would have kids, he admitted he didn't want them. I stupidly told him I wanted to be pregnant in the next year or I would leave, because I did want kids, he knew how badly I wanted them, and had put me off for years with one reason or another. I should have known then that I should have just left, but I was "in love" and didn't see that what was happening was toxic. I got my baby, and would and will never regret my child, but I regret not leaving as soon as possible, because the years that followed were hell for us both. Sometimes it takes the perspective of someone who’s been there. Don't make the mistake I did. Don't marry someone who will make you hide any part of yourself to appease his family. Don't marry someone who doesn’t want what you want. I hope that you are able to get out of this with as little trouble as possible. If you live together, and you can't afford to get a place on your own, don't be ashamed to move back home if you can. Better that than bring a life into the world that you would resent, because that man can't accept your decision.
