I don't think you really love your wife cos if you do her past won't affect your actions. You are judging her for telling you the truth. You need to work on yourself cos even if you divorce her you will also not trust the next woman you marry cos u will still have de same tots. The next woman might even have a more horrible past. If u want your marriage to work its in your hands.

Your story is a sad one but not new. Trust me women are going through worse things in some marriages. A lot of people feel divorce is a easy one and always the answer to all marital problems but let it be your last resort. You have to be a woman married with at least a child before anyone can really understand how you feel.

My advice to u is to try as much as possible to find a way to develop yourself not because of what he says but to guarantee a better future for your child, You also need to save no matter how difficult it is. One day your husband will look you in the eye and ask you if he collects your salary from you without blinking an eye despite d fact that he knows what you do with it.
There is also a huge possibility he has met someone he's dating probably a single mother who is independent and he keeps comparing you to her. U also need to involve your family in this cos dey would be your moral support and assist you is prayers. Like u ve also been advised look for someone he respects so much to talk to him but avoid your pastor cos he would run away from church and you will find it difficult to bring him back to church. Its not easy but you have to put in more effort .Don't give up on the marriage as there is noting God can't do. Trust me am talking from experience.
