I would say to prepare yourself for both scenarios, being separated and a time might come that either one of you will declare that it is not possible to continue to live together.

 

In most of such cases, people put sacrifice and here it is from both you and her for the sake of the child, in which indeed, the best for him to care physically and mentally is for both of you to stay together.

 

Staying together can be supported by counseling either spiritually by an Imam or to seek it professionally by an expert. I would really recommend this as a way to either heal issues or at least minimize its mental stress on both of you so you can enjoy the relationship or at least make less problematic.

 

But at the same time, if either decided this relation cannot continue, it happens. You need to obtain court divorce papers and take it to your local Imam to finalize it islamically. The judge will rule over custody, child support, caring and visitations etc. But as Allah the Almighty said, divorce should be in (Ihsan) excellence. Meaning you do more to your son as a father than what a court will tell you.

 

I hope and pray Allah the Almighty will bring the best for you both and your son, ameen.

 

Almighty Allah knows best.
