Truth About Deception

My husband and I have been married for less than a year and I've fallen out of love with him. Prior to us ever moving in together or getting really serious I was upfront with him and told him exactly what I expected of him if he wanted to be with me and what I would not ever tolerate in a relationship. I told him that if he wasn't comfortable with what I needed or had doubts about being able to be that person, then we shouldn't make a life together. He promised me he could be the man that I needed, but he continually lied to me. Each time I found out he was lying, I was heartbroken and suggested we go our separate ways, but he'd break down to tears begging me to stay, promising me he would change. From the very beginning I have been completely honest with him and told him I could not be with a man that has no integrity... still I married him because he promised me that our issues were behind us. A few months ago I realized he's been lying to me all along. I resent him for marrying me when he had no intention of changing, and when he clearly longed to be sexual with other women, I resent him for ruining my trust, my self-confidence and our marriage. I'm depressed and I don't know what to do. I still care for him deeply and pray that somehow we can work past this and that I will fall in love with him again, but I fear that he will never change and our relationship has been so badly damaged that I don't know if I'm capable of ever trusting him again. I don't want to spend my life being unhappy under the constant worry that my husband is an unfaithful liar. I'm afraid of losing him, but I'm also afraid of losing myself and any chance at happiness if I stay.
