I am not happy after marriage, I feel something is missing in my life, 4 months back I got married, we didn’t go out, we don’t have complete sex relationship, I stay with my in-laws, I am feeling alone in that house, I want to forget all these things and live happily.

You have all reasons to feel unhappy; anyone in your situation will feel the same way. You cannot forget all this instantly, only passage of time can make this possible and that too if situation improves. You should talk about your feelings to your husband and both of you have to find out solution jointly.
