Worthless

I honestly feel worthless, my fiancé of 2 years left me yesterday and we are expecting another baby July 15th 2018. We have a 5 month old and she’s my everything I’m trying so hard to keep everything together, when I start crying she’ll start crying. He said mean things to me saying I was fake and that he didn’t love me and that I was controlling - reason for that is because the start of our relationship he had cheated on me and I didn’t want him to have certain girl who he had cheated on me with or girls who had a thing with him back then and etc said I was insecure and jealous which I’m not denying that at all. My world just fell apart i wanted nothing more then to work on our relationship I love this man to death.. I do deserve better but I feel like I am worthless that I’m not good enough...
