@Farlene,
If you can't raise important issues with him now, what makes you think you will be able to raise them with him the day after you get married? And what makes you think the dishonesty will end the minute he says, "I do"? Don't you think you deserve at least basic honesty from someone who you want to be with for as long as possible?
Trust is one of the most important values in a relationship.
You say the wedding has already been put off once. And you already have all of the paraphernalia that go along with it. I have been working in the wedding industry for a few years, and I know
for a fact that it takes a good month or more to purchase most of that stuff because rings have to be fitted and apparel has to be tailored. And it also takes at least some time because nearly no one finds what they want on the first try, as there are so many choices and everyone wants to look and feel their best.
This means that either everything is bargain basement off the rack or he was planning this all along (and has been dictating all of the choices to you, without giving you a say in the matter), because a competent wedding professional such as a bridal gown or suit or sari seller or a jeweler would at least care about fit.
Consider what that means to you. Of course weddings don't have to be incredibly expensive affairs; I am not suggesting that. Rather, I am suggesting that this is a steamroller.
You say you don't have the guts to confront him about lying. You are not going to magically grow guts when you put on that ring.
You are also not necessarily going to go through life quite as enthusiastic about raising his kids as you are right now.
You might even wonder, at some point in time, what it would have been like to have ended up with someone else.
Extricating yourself from an engagement (even when the rings, etc have been purchased) is a
helluva lot easier and cheaper than a divorce.
I have been married for nearly 25 years and I trust my husband implicitly. We also got married in our late twenties, and he didn't propose until we had been dating a year. We knew (and still know) that we love each other, but we wanted to be certain. Nobody steamrolled anyone. We both knew we wanted to be together. He didn't lie to me then, and he doesn't lie to me now.
I know you're going to tell me - oh but I love him - and all of that. Relationships go through honeymoon phases. You're in it right now. But there are already red flags. If you delay for a while you will learn whether you can continue once the bloom is off the rose. You'll learn whether you can continue to put up with stuff that a lot of women would never tolerate. And maybe you'll grow a spine and figure out how to confront him about his untruths.
I'm sorry if that feels harsh, but my motive here isn't to stop marriage. I love marriage. Right and good and trusting and loving marriage is fantastic.
That isn't what you've got here.
