<human>: My boyfriend (we'll call him Allen) and I have been together almost a year. It's been rocky for some of it because of my jealously and insecurity issues. I've been working on myself and have been trying to let my issues go for the sake of our relationship. Last night, I slipped up. I don't want to go into detail of how, but basically it showed him I still don't fully trust him (even though there's no reason for me not to).  He told me he's done forever. I tried sending him a heartfelt apology email and haven't heard anything.

I am completely heartbroken and I hate myself for what I've done. I've been in a handful of serious relationships in the past and I never felt about them the way I do about Allen. I truly believed he was "the one" and we would be together forever. Other than my issues we had the greatest relationship; one that I had fantasized about and wanted since I was a little girl. He supported me through really hard times in my life and became my best friend I've ever had. I love him endlessly and I don't know how I'm supposed to continue my life without him.

How do I move on? Even thinking about trying to date again eventually or be with another man makes me sick to my stomach. All I can see is Allen's face when I try to even imagine there could be someone else. I don't know what I'm supposed to do. I feel completely lost and I feel like I'm going to be alone for the rest of my life now if I can't have Allen. Some people may think I'm being over dramatic but I really feel strongly about him. It's killing me inside that I have ruined this and he doesn't want me anymore. I just want to move on and I don't think I can.

Give me the gist of the text in a nutshell
<bot>: I hurt the love of my life and I don't think he's going to come back. How do I cope?
