Advice on divorce and separation

Hello, I’d like to seek legal advice from your team. Few months ago I got a news which was verified and admitted by my wife about her infidelity and fling with a colleague at her workplace in Abu Dhabi. I stay at Bangalore and she at Abu Dhabiand due to professional bindings we meet every month.. now she has delivered a baby girl and currently she on maternity leave and staying with her parents in Pune.. whereas I stay at Bangalore with my parents.. her parents Know everything.. I have forgiven her after she acknowledged and realised the wrong doings.. now that I’m planning to get her to Bangalore to which she is resisting with all sort of lame excuses.. now I’m worried on the repercussion after she comes here.. earlier during the fling when she used to visit Bangalore there used to fight with no valid reason and she warning to file police complain against my family we don’t agree to her terms at home.. now she is claiming that child is not mine. Is it possible to send legal notice.?
