DV act time limit query

Dear Lawyers n friends, My wife left me after 4months of marriage on her own will with pride. Now it's been 1.5 years. During this 1.5 years her uncle called me periodically n asked for divorce with ransom. I had agreed for divorce but I denied for money telling I haven't haven't taken a rupee from you, so I won't give anything. Now she sent lawyer's notice claiming I threw her out n did harassment. And her uncle called me to tell me to take her back. She claims to file extortion package (DV, crpc125, 498a, 304,506,24 etc). I didn't respond. My questions Q1: DV: there's judgement saying DV not maintainable after 1 year. Does it applies in my case as I'm not in contact with her since 1.5 year? Or her uncle's contact is considered to rule out 1 year ? Q2: Can she file multiple cases without any evidences ? TnR, Arjun
