ex-boyfriend

So, I recently just got out of the most serious relationship i’ve ever been in. He cheated and I have taken it really hard. We weren’t together for very long, but in that time I fell completely in love with him. In a way I didn’t even think was possible for me. I’ve had several dreams about him and even considered calling him a few times. Cheating is the one thing i cannot deal with. I told him that when we first started dating and he did it anyways knowing my past and how much it’s impacted my life so negatively. He was the only man I’ve ever seen a future with. We talked about moving in together next year, getting a dog together, having our dream house and kids one day. Before him I didn’t even want kids, but I wanted kids with him. I wanted a life I had never even thought about before with him. I feel so broken and alone. My friends and family would literally kill me if I got back together with him, but should I at least talk to him? Should I try? Getting hurt by him was torture, but living without him is becoming unbearable and I don’t know what to do. I know I deserve better and I could find someone else, but there’s only one him.
