Worst Valentine's day ever

So let me start off by saying I am sixteen weeks pregnant. Well anyways as I am sitting here doing my hair and makeup and trying to find the perfect outfit for my date night with my man my phone goes off repeatedly. As I open the texts from a girl named Alyssa and my sister I cant help but to breakdown at what I'm reading. I was informed that my man had a date night with this Alyssa last night and that he has had her on the side while being with me:( the worst part is that he told her that I'm a slut and a cheater and that the baby I am carrying isn't his when we were together at the time I became pregnant! How can you do that to someone you love and who blessed you with a child?:( The tears are rumbling down my face. Mascara smeared along with cover up. Face stings and burns at embarrassment as I feel stupid. I feel so small and empty and all I wanna do is curl up in a ball and disappear. And everyone wonders why I absolutely hate this holiday!
