I can't believe this

My boyfriend who I have been dating for almost a year I just gave birth Nov 26th !!! We live together and everything he would do this. And his sorry ass keeps trying to make me feel bad and saying it's a ex.. they haven't done anything haven't met up or shit . I'm so fucking sick of this I did not get all the messages, especially the one where she's thinking about him in the bath && constantly calling him bae etc .. I was in a hurry to send to me before he got back, and they are talking about dope which I chewed his ass out about too
