First time mom looking for advice.

Savannah

I just found out I was pregnant on June 26th, 2019. I was overwhelmed because it is a new relationship and we've barley been together a month. I fell for this guy really hard and just found out today that he's been cheating and lying. So how am I supposed to do with these feelings I have? The test was my first morning pee and the photo was taken minutes after the results were there. I was super excited that I would be expecting my first child but now I can't believe he's cheating. The most messed up part is that he also knew the same time I did, yet yesterday I caught him talking to another girl. He talked to her for hours on end. So while he was sleeping I went thru his phone and found out that he deleted the messages between her and him. So today I messaged her telling her I was pregnant and that it was his. She had no clue we were dating. I have a bunch of crazy emotions and unsure how to even process the fact that maybe I will be raising this child on my own. So I really need some mom advice. Should I try to talk it out or should I walk away?
