Wife has Vaginismus. Will Indian laws help me get divorce without alimony.

Wife has Vaginismus and takes no effor to take treatment and cure it since last 5 yrs.

I am done being in sexless marriage. Atuls case has motivated me to seek options to get out of this messy situation. If i chooses to divorce her will I be liable for alimony and maintenance?

Edit : We do have intimate moments but no PIV.

Edit 2 : Too many hate comments in personal chats just because i decide to put myself first.
