Some advice from someone in your DS's father's shoes.
My wife walked out on me when our DS was only 4 months old because she simply decided she had made a mistake and went to go and live with her parents in the SW of england (I am in London) who then chose to turn her against me.
There was no occurrence or accusation of DV or any type of welfare concern; her and her parents simply decided I couldn't or shouldn't see my DS.
What the occurred was 3 months when I was only permitted to see my son, who I adore, for only 6 hours. (he is now 20 months)
I would email regularly requesting updates on him and received nothing.
I sent little cards to him and presents when I'd been away for work; these all got returned; so I made a keepsake box for him to show him that I was always thinking of him.
I kept asking for more contact and was told 'no - you'll only get contact as and when we decide'
Through all of this, I towed the party line, I wanted my wife back despite her behaving in such a grotesque way and only thinking of herself. I knew the best situation was for our DS to have both parents in his life, together. As time went by, it became clearer through emotional and financial abuse on her part - refusing to let me see our DS unless I rented her a cottage to live in or bought her a car (I pay far more in CSA monies than required and pay her spousal maintence as she can't find a job despite her having a large amount of capital) - that she simply didn't want anything.
I met with my solicitor, explained my side of things, showed them the email and we started the divorce proceedings; we also started the contact proceedings - let me tell you what happened - and this was ordered when he was 8 months old: -
1: She was made to let me have contact every other weekend.
2: I get 8 weeks of holidays a year in a maximum of two week chunks.
3: She has to drive him to London for every contact period and has to pick him up at the end of it
4: She has to FaceTime him with me twice during each week (I have to do the same when we are on holiday).
5: She has to (as I have PR) keep me informed of all medical appointments - she had been deciding medical care without consulting me - and his GP also has to inform me when DS has seen him.
6: She had to pay ALL the costs of the court. Not just her solicitor and barrister's fees but mine also; the court saw her as someone who was obstructive, deceitful, cruel and acting no way in our DS's best interest and he made an award to costs as he saw her wasting his time and the courts time and imposing untold damage on our DS in not allowing proper contact. My legals cost me 14k - her's will have been about the same so it cost her, ballpark, 30k to have to give me exactly what I had been asking.
My advice to you is this: -
1: Do not go to court - if you can't stand your ex now you will hate him even more when you lose - and you will lose.
2: Go to arbitration (not mediation as it is not binding).
3: Give him PR.
4: Put his name on the birth certificate.
5:Agree that he should have contact (out of a contact centre as that is just not justified), this contact should be little and often (not every other week but every week building up.
6:Overnight contact should occur very quickly
7: After about 5-6 months he should be able to take DS away on holiday.
8: Start thinking of your son, not about you. This will sound harsh - no matter how much you hate your ex if you love your son you will want him to have a relationship with his father. Research shows that children who have access to two parents when they are growing up (whether together or not) have a better and more balanced upbringing and a brighter start to their life. Do it for your son.
The reason I give the above is it is exactly what a court will make you do and if you then break that order, you face a fine, community service or, for repeat offences, prison - in which case you will not be seeing your son.
