At the very outset I do acknowledge that your case is a little complicated. Lots of people involved. But, many people face similar situations. With people working in different cities and even countries, it is quite normal to have proximate relationships. But, you said that this Singaporean girl was only a girl-friend though you did have your share of fun, kissing and other stuff.. whatever the case may be, if you havenít been physical with her (in the obvious sense of the term) you are not guilty of adultery as the basic requisite for adultery is having intercourse with another woman.
According to a recent Supreme Court judgment, delivered by a bench of Justices K S Radhakrishnan and P C Ghose the mere fact that the husband has developed some intimacy with another, during the subsistence of marriage, and failed to discharge his marital obligations, as such would not amount to cruelty. So, the case under Section 498A of IPC is not made out.
Also, in this case in your words you have not indulged in adultery and your wife apparently is not in the possession of those alleged pictures, she cannot claim divorce on the grounds of adultery and as I have pointed out above, as per the Supreme Court even the case under 498A is not made out. Additionally, the fact that you have been providing for her residence and upbringing of two daughters from her earlier marriage would also go on to show to a great extent that there seems to be no inclination on your part to seek dowry, as is evident from your conduct.
The fact that she is not allowing you to see your son and she is also not willing to live with you is slightly troublesome, but this is something which can be solved with negotiation. As, they have nothing against you, and are merely issuing empty threats, you can make the things clear to your wife and her family and assure them that you want this marriage to work out and you are still faithful to her as you always were. I am sure they will see reason in that. With respect to the threat to your life, you should try talking to them and even after that you feel the threat is real, then you may have to take a strong decision and make provisions for your safety even if that amounts to approaching police for the same.
