Rape case

Hi, I'm looking for some clarification for IPC 376, 506 on the following points.... Rahul met Neha about 4 years ago and initiated frenship, during frenshp he attempted physical contacts on several occasions and however the girl denied, post which he proposed marraige to her, still girl didnot agree to get physical and asked families to be involved..however on one accasion when Neha was unwell with fever Rahul met her at her home and they had physical contact after Rahul forced her.. Since, then Rahul and Neha stoppped interacting however Rahul again approached Neha after some months to initiate a business through Neha's Father as her father was a doctor and he wanted to open a dialysis center... Rahul has been friendly with Neha again..and apologised for previous behaviour and offered to marry her... Neha therefore assited him to open the business through her father.. her father has witnessed the agreement of the business as well howevr no money is involved from father's end just his contacts and expertise and time....During the time the business was been installed Rahul continued to have physical relation with her and once the business was set he stopped all contacts with Neha... Neha got pregnant and tried to contact Rahul howevr he never responded as a result of whch she aborted... Rahul's father passed away during this time so Neha stepped back... however after 1.5 yrs several people told Neha that rahul was alredy married while he was with Neha and had been cheating her all the while.... Neha ended up filing an FIR as a result of this for IPC 376 against Rahul for being married and hiding the identity...after FIR filed same frens who quoted Rahul is married change their version saying he isnt married....... Rahul has received condition interim bail in the 1st attempt of no contact with Neha...and on the next date got interim bail till chargesheet filed... chargesheet got filed today.......... Rahul is offering money to Neha to close the case however Neha is seeking marraige for her honour... what are the chances of Rahul's convinction in this case and if Rahul agrees to marry how can the case be withdrawn after the marraige...
