When you fall in love it is like a temporary madness, it erupts like an earth quake and then subsides and then you have to make a decision. You have to work out if your roots have become so entwined, it is inconceivable and you have to part.
Because, this is what love is. Love is not something that leaves you breathless, it is not excitement, it is not a desire to make love every second of the day and it is not lying awake at night, imagining your lover is kissing every part of your body.
That is just being 'in love', any of us can convince ourselves we are 'in love'. Love itself is what is left over when being 'in love' has burnt away. Doesn't sound very exciting but it is.
Have you asked yourself the question, do you love your wife? If you do, then pick a flower on your way home every now and again. If she is cold, wrap her in a warm jumper. It is what love is. It is a friend, a lover and someone who will be there for you.
