My baby dad has been keeping numbers blocked to talk to them well he’s away from me .... I asked him about it and he said he didn’t know the numbers I kept bugging him and told him I already knew who they were ... he said they were only FRIENDS and he meet them from work... but that they didn’t know about me and him or our son on the way (I live with him and have for 2 years) I felt like there was definitely more to the story since he didn’t just come clean in the first place ... here are 2 of the 4 girls responses to if they talk and about what

The other 2 girls got very defensive and said no the one blocked me right away ... am I over reacting ? How should I handle this I want to ask him again tonight to just be honest and tell me that he was trying to flirt and it wasn’t just for friends but I already know he’ll denying it and it will just cause another big fight (I’m 33 weeks pregnant and really can’t handle the extra stress)
