Aww bless you sweetheart, I hadn't realised there was a marriage in there too.. That's a lot of disappointment all at the same time.
I wonder if a period of 'time off' might be good for a while as well then?
I remember this particular relationship I had, where I really wanted it to irk out and had increasingly worse doubts about it. It was like having a prism that I turned and turned and could never get to look (for long) how I wanted it to look. I lerned the hard way to put it down.
If you are having massive doubts and fears about your future and life in her email, take some time out. Maybe no new relationships for a while. Certainly get your behaviour back on track for you are happy being, and offer an apology to whoever / the universe for what you did under pressure, and then move on, the wiser. I think we all do things we regret under certain conditions, and it is to be learnt from and I think we become kinder and more forging to others and ourselves when we think it through.
Also think about your intuition and what / when it led to believes certain things. I learnt that what I began to sense was what eventually happened in the end. I could have listened at first and saved myself heartache, or I could have muddle on pretending I did not know what I actually did know. Maybe bow to give more credence to yourself and what you sense, your own wisdom.
I really do swear by self esteem stuff tho. Saying nice things and thinking them, means we are making nice energy. It feels nice to think and say nice things, and it encourages us to be those nice things. If you are suffering depression, it is important to be gentle and affirming, and offer hope and solace. You are not alone.
I find it helps to make a little plan for the future, and factor in stuff you need to do now. Could you make a plan of things you could start doing tonight, like eat well, sleep, get some exercise every day, treat yourself well somehow? And then changes you want to make to your personality, to get back what he cut off? And the maybe goals for your life, like a truly decent relationship when the time is right, and meanwhile some study or travel, or something with the kids? All with a mantra of 'I am a good person' going on in the background?
Remember there is more to life than relationships. A wise woman won't let them knock her too much, yet it is ok to cry for something you loved and lost, as it will pass.
