Marital problems

I am a 29 years old married male, married against my will (parents pressure) since last 3 years and suffering from depression since last 3 years because of it. I have a 9 months old daughter but my sexual satisfaction is not there. My wife really loves me but I unable love her back (never liked her face). I am emotionally destroyed because I really feel empty inside. I am planning to do a second marriage and for this purpose I ask a girl at my office whom I really like (she likes me too) but she is saying that I should leave my wife behind or make an agreement with her that I will spend only one day a week and the rest 6 with my second (probable) wife. I can't do this because I have heard that there is extreme punishment for inequality between wives and I am not that stone hearted to do so either, and now that girl has stopped talking with me and I am in intense depression. I can't work at my office properly, finding it hard to follow Deen because my mind is seriously disturbed since last 3 years. I wish I could die right now because its really seems impossible for me to live like this and still following Deen completely. Please make a dua for me and give me a solution.
