<human>: Condense the text into a few key points

I'm heartbroken [35F] because the man I was in love with [29M] and thought I would be with for the rest of my life, left me after I miscarried our baby and found a new girlfriend less than a month after the miscarriage. 

We were together for 10 months but a few months ago he asked to get married and start a family sooner rather than later. 

He told me that I'm too sad to be around and that I need more support than he could possibly give me. He also told me that he deserves to be happy and find a woman who will give him the family he wants more now than ever.
<bot>: No baby and no partner. Feel lost and heartbroken. How can I heal and move forward during this difficult time? Why did my ex abandon me during this painful time?
