Answer:
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad 
is His Slave and Messenger.
First of all, we say that some jealousy is commendable and some jealousy is blameworthy. Jealousy that leads a wife to harbor suspicions about her husband without a sound reason is blameworthy jealousy. To learn how to treat women's jealousy please refer to Fatwa 90757.
Also, for benefit on how a wife should treat her jealousy toward her husband’s ex-wife, please refer to Fatwa 160431.
With regard to your wife's suspicions about your son not being your real son, they are evil and you must advise her about it. It is a grave major sin to make accusations regarding someone's lineage and honor. Abu Hurayrah 
narrated that the Prophet said: "Two things are signs of disbelief on the part of those who indulge in them: slandering people's lineage and wailing over the dead.'' [Ahmad and Muslim] Imam An-Nawawi 
said in his commentary on this Hadeeth: “This Hadeeth affirms an emphatic prohibition of slandering someone's lineage.”
Besides, it is not permissible to take DNA tests to confirm a lineage that is already legitimately confirmed.
On the other hand, your wife has the right to refuse that your child stays with her in her home unless he is small and he does not have a caretaker other than you. However, she has no right to abuse your son and describe him as the son of a b....; this is slander and she must repent from it. For benefit on the conditions of repentance, please refer to Fatwa 86527.
As regards the duties of each of the husband and wife toward the children of the other from another marriage, then we have already explained this in Fatwa 97216.
In conclusion, we advise you to be wise and not resort to divorce as long as possible, and if you can rent a big house so that your son will be close to you and you can look after him, then that would be good. For more benefit, please refer to Fatwa 92474.
Allaah Knows best.
