My ex left when I was pregnant. He was very clear that he wouldn't be involved if I kept the baby as he had a new girlfriend (and also disputed paternity). As an older woman with no other children I wasn't prepared to abort. I informed him of my decison and recieved very abusive texts from her.
I went on to have my child and never saw/contacted them again (they moved away). I didn't bother with CSA as I have been in full time work since having him and he didn't reply to the request for a DNA sample (which I paid for - was very angry they thought I'd lie about paternity).
Now she's back. I have no idea if they are together or not but's it's only a matter of time before we bump into each other. It was such a horrid time and it's not really over as we haven't proved paternity. I was really happy and now it all feels Jeremy Kyle again.
Don't want to get involved but does ignoring her make me look churlish? Should I be ttracking ex for DNA or leave it up to my son to decide when he's old enough.
