well you look like a nice couple however I spent a couple years living in india, met many families, attended many weddings and so I know those "looks" can be very deceiving. it's the same everywhere. Seems nearly everyone is pretending to be happy because everyone else around them seems to be so well adjusted to the lunacy of life on this planet. It's good you have some time apart to process your situation and to think for yourself. Children can make just about any relationship tolerable but what's the point of life if all you can do is tolerate it? Soo here's my two cents worth of advice.
Making this relationship work is NOT your responsibility however it IS within your power to do so. You do not accomplish this giving in and being the good wife, this just makes you "tolerable" to him and generally will make life increasingly intolerable for you. This is healthy for no one, least of all your child. So what to do?
Listening is an all but lost art on this planet however the benefits of truly listening to others can not be calculated. The art of listening is can be simply put as placing your whole attention on every word coming from your partners mouth in an effort to understand what it is they are saying, the whole concept, the big picture, but to do accomplish this you must CLEAR YOUR MIND of all REACTIONto his words.
So if he says something and you think to yourself, "oh yes this is true, i agree" or "no he's crazy, what is this nonsense coming from his mouth", Then YOU are NOT LISTENING, you are reacting, you are responding, you are attempting to frame his words within your comfort zone of what is acceptable and not acceptable. To truly listen to someone and really understand where they are coming from, you must listen and listen only. Any thoughts that arise as a response to his words are a distraction, interference. as you develope this skill you will begin to see everyone differently, and whats more they will see you differently. it's such a rare thing that when someone discovers a person who can truly listend, then there ability to listen TO YOU rises to match yours and then the real magic happens. The outcome who can say but what is sure is you will both be better people for it, happier people for it. If you would like to know more i suggest looking up Krishnamurti on Youtube.
