Dear Heart2Heart, my wife and I have been together for some time now and we have a child together. However, of late, her behaviour has changed. She no longer sleeps in our bed but in the sitting room, she does not like to get intimate yet when we do, I find myself on treatment for STIs. Mind you, even through all this, I have never been tempted to cheat on her. I love my wife but I do not think she is faithful or in this marriage for the long-term. What should I do? Anonymous
