My marriage is not perfect, there isn't any affection and we just sort of get on with it. There is a lot of built up resentment, combined with no sex life, separate rooms. There are very young children, 3 and a baby, to worry about. My son (3) asked me today why mummy doesn't love daddy, if daddy loves mummy and why isn't mummy happy. My heart just sunk, I didn't think he knew. I thought we kept it all together in front of them. I can't cope on my own with two this little. I can't afford to leave. We can't afford two households. But how unreasonable would I be to stay now I have proof he is affected?
