Meeting my daughter

best efforts to pursued your marriage is as you already tried yourself why not involve a third person if this process is not done let that person may be her close friend, relative, her parents, an elderly person to have a discuss to make things right for you to solve this issue

because from your words its seems you want to be happy then if this process is not fruitful then try legally by filing guardians and wards act for visitation rights  

Can the Guardians & Wards act be used for visitation in this case? I dont want to use it if my wife relents,  but may have no option as its already been 1.5 years. 

Ur wife is in quandary to live or not to live with you, whereas you want to have relationship intact. Ur daughter is going to be a living bridge to rub-off all the differences and bring spring in your matrimonial life.  Guardian and wards Act is the correct and the best solution for you.  File a case and seek visiting rights atleast once (ask for two evenings of two hours each) in the front hall of the house where your wife is residing.  The court will certainly grant the visitation rights to you atleast once in a week.  Use these visitation rights to enjoy the company of your daught er and not to forget, use these meetings to mellow your wife and to remove all her grievances against you and pick out the pinpricks and  resume matrimonial life.  Unlike in other cases, the visitation rights to be allowed in your case should serve double purposes as explained above.
