Smelling something fishy

Jessica
I'm 3 months pregnant!❤️ happy as can been buttttttt I'm smelling something fishy coming from baby daddy who I'm currently with, this evening at work we go to lunch at 2am, we'll all sudden his phone rings .. Who in the hell is calling at 2am , so he tells me it's his buddy Sam , but now I'm sitting here with him and he's playing a card game with his friends at lunch but he has his phone hidden under the table and somebody Keeps texting him but he won't pull it out from under the table . I've had trust issue with him b4 and now I feel like it's not getting any better . Would you think something is up if your SO was hiding his phone and receiving phone calls at 2am ?? Help ladies
