I will try and keep this as short as possible though I'm absolutely fuming! So me and my son's dad split up in March and he's finally moved on which I found out tonight and is fine I genuinely hope he's happy however I've found out from other people messaging me as he didn't have the balls to tell me himself! My son and hers have had playdates and she's put pictures on Facebook! I've asked him to tell her to remove them and to not put any more but am yet to receive a reply, he's also been buying her children clothes and things when I provide everything for our son even when he's at his though he does pay me some maintenance! When he dropped him back the other day my mom asked what they'd done and he said just chilled at home which is an obvious lie and something he does a lot! So aibu for thinking he should have waited longer to introduce our son? I'm really worried it will confuse him as he's only a baby
