A bit of backstory here, just a teensy smidgen
My ex left me when I was 36 weeks pregnant for the Woman he cheated on me with. He told me that he wanted nothing to do with my Son even though he'd seemed interested although I am now seeing that it was a ploy to keep me calm while I was so heavily pregnant. I said fine because I knew I'd dodged a major bullet. I don't want my Son to grow up and cheat on women so I showed my ex where the door was and let it hit him in the back as he walked through
I met my current boyfriend just after I'd given birth through a mutual friend. We hit it off but agreed that we'd just be friends because I was a new Mum and my crazy self was absolutely mad.
We have been together for just over eighteen months and my Son has started calling my new boyfriend "Dada" He's been the only real male in my little boy's life and I'm completely fine with this happening. But my ex is now suddenly cropping up from whatever hole he came from claiming my son is his and he should be called Daddy.
AIBU to tell my ex to do one - He's had zero contact and wanted nothing to do with my son until recently (Past few months) I only think he's come crawling back because Miss. Airhead blonde bimbo has chucked him for someone else
