MY SONS DAD

*4 years ago* 
So basically, we were both 16 when I feel pregnant and we BOTH decided not to have an abortion. 
When he told his mum I was pregnant, she said she was going to kick the bairn (child for people that don't stay in Scotland) out of me and make sure I could never fall pregnant again. When she told me this I was on my way to college. When he found out about this, he told me to have an abortion and I said no and I left him (all this happened when I was 5-8 weeks pregnant) so after 2 months, I started seeing someone else and when my sons dad found out, he smashed up his car. That night, I was told to keep my son AWAY from his dad till after his court date (which was a year after) if I did, social work would be involved which I didn't want so I had 0 contact with him, when he found out I gave birth, he went mental, anyway recently (my son is now 3) he is blaming me for him not having a bond with my son, although after the court case he was aloud to see my son, but he would rather spend time with his friends and new 15 year old girl friend (we're both 20 now), I have begged and begged him to spend time with my son, I've tried to take him to court and everything but he's having none of it. 
Basically I don't see how it's my fault HE doesn't make the effort to contact me?? He'll phone me if he argues with his gf although I don't answer. He said he can't give me child support because he has no money but bough his girlfriend MAC makeup two pairs of uggs for Christmas and didn't buy anything for my sons Christmas... 
Am I in the wrong??? 
PS the guy I started seeing, we didn't work out because of my sons dad, he out way to much pressure on the relationship. 
I am seeing someone else who is AMAZING
