Leaving DS dad - What to do next

Hi This is my first post.

I have a beautiful son aged 16 months.

I really don't know where to start.

I haven't yet left my DS dad, but I will be as I cannot be with this person any longer. He is aggressive, rude, impatient etc... when he last had therapy, they suspected he was suffering from PTSD. He has since made no effort to seek help for this. I have tried to be understanding and patient, but I have quickly realised that its not just PTSD, he is just an a**. He calls any woman dressed up a sl** and believes that all women should be at home cooking.

He has no patience when it comes to DS, he has no time for him what so ever. He shouts at DS every time he cries or has a mini tantrum. My son deserves to be loved, not to be an inconvenience to his dad. My son cannot and will not be brought up thinking women do everything, homosexual relationships are wrong, mixed ethnicity relationships are wrong, the guy is totally deluded.

I am so disappointed in myself for being with this person.

What will happen when we break up? What options do I have?

Thank you for reading.
