Is this a bad sign how I feel?

I wish you had asked for advice here a year ago. Mine would have been, "If you're in love with your ex, don't marry your fiance." By marrying your husband under the cirstances you describe, you have placed an incredibly unrealistic expectation on your marriage. The first year of marriage is hard on normal, loving relationships. Yours isn't normal, so I think you're getting exactly what you should have expected.
