The person will be a physic disorder of having doubts on his partner. Thats why tracking the phone, placing camera at room etc, the most interesting thing is that he doesnt even have doubts on his mother also. So he is tracking her mothers phone by gifting a new phone.think of his doubting nature ? Need immediate attention on your actions and behaviors.
If you having such doubts, then why should you want the child. Why cant you go for a dna test and confirm that to.
You and your family didn't have any shame on saying such cheap and unethicial thing like this. Saying bad words is not a good thing or having any good character. Saying that to other person such that i have beaten my wife, said such bad words, did you have any shame on saying so. Good mannered people will not harm their wife or use bad words. It is not a pride thing to say to others also.
