I split up with my ex nearly 3 years ago after being together for 6 years and have a DS age 3 together. He cheated on me with his current partner and now they are expecting a baby. I completly moved on, I've been dating and had couple of relationships myself but nothing too serious. Despite the fact that ex cheated on me we get on and i see it as being mature. Even thought breakup was really though and i felt betrayed at the time but looking at it from where i am in life now i think it was for the better.
We've always used snapchat as main communication form to send pics and videos of DS, even when i found out he cheated on me i carry on sending him pics and videos of his child (ex was asking for it as well) so our snapstreak got quite high as we have been doing it everyday for few years. His partner is fine about it as well, no problem there.
I've been seeing someone for 6 months now and i've been honest about it but he literally said that its him or my ex and the snapstreak so my question is have i completly lost touch with the reality and AIBU or is he overreacting a little bit? There is completly nothing between ex and myself, i do not find him attractive at all which i told my current partner and snaps are ONLY of our child.
