Heartbroken, Defeated & Alone

Lei

So I just found out my partner of 4years has been texting other females and inviting them over to his place. My heart raced instantly when I found out as I was enraged with anger, pain and disbelief. I ended it right then and there as he tried to justify the bullshit! Now that's he's gone, I feel like there's nothing left for me. I've dedicated so much time and pretty much centered my life around him unintentionally, to find that I'm all alone. And rather than be vengeful, I really just want to move on with my life. Afraid that I'll never be able to move forward with anyome else or that there won't even be anyone else. I mean I don't even know where to find anyone else. I'm pretty sure jumping into someone else's arms wouldn't be the best thing anyway, but eventually (once my heart has healed) it's bound to happen. Anyone have any advice on how to move forward?
