Should I leave him?

Based on my comments,

For love, relationship/marriage, family to progress in good path would you suggest...

1) Distance myself from him. Let him do whatever he wants, and I will do whatever. This will involve me spending time by myself - shopping, watching movies, etc and also time/days at my parents place. call him less, etc.

2) Try to be happier in relationship and be closer to him. by asking him to sleep in same bed, i will cook regardless, and be spending more time together and call him more.

Your relationship seems very calculated, are you in love with each other? Would you miss him if you left? It doesn't sound like you are happy together, and it doesn't sound like you care to fix things. So I think you've answered your own question. I am more concerned about your future child having two immature, incompatible parents. My suggestion is to do whatever it takes to be totally content with your life before having a child, and only you will know which route will take you there. Best wishes!
