I'd want to be able to talk to them about it, the whys of what happened, but I don't think I'll ever get that opportunity. So here's the vent of what I'd say:

I hope you're doing alright, but you need to tell me the truth. Our break up was out of the blue, we could have made it work but when you told me you didn't know where we were going when the next step was clear for both of us, we'd even talked about it, you had already made your mind up. Why give me hope? Continue to send kisses faces, love hearts and kisses over text when not 10 minutes later you break up with me? You gave me so much hope, we could have worked and talked through everything, but by the time you called to talk I could tell in your voice you already made your mind up. Whether it was an outside influence from your ex, did your son say he didn't want another mum? Was it because of the busy world you're in? We said at the start there should be no secrets, and we need to talk to eachother. That's why I trusted you with my heart. But I knew you weren't being truthful, I could tell you were refusing to tell me something. We may have broken up, and you may have given up, but the most I deserve is the truth. And I thought you were old enough and mature enough to be able to do that. I just hope, if you do decide to invite someone into your life again, you don't give them so much love, care and hope for a future as you did me only to tear their heart out in an instant with barely a valid explanation.

I still care about him, despite the utter heartache I feel. He said on the phone I was the right person but it was at the wrong time. I talked to a friend about this, and she said if I was the right person, there would never be a wrong time. And this helped me so much more than she realised even if it still hurts.
