I want to tell my story and hear other peoples.

So i want to tell me story and see if people think its wrong, id love to hear other peoples stories so please feel welcome. I'd been with my partner for 4 years, we had been TTC for 6 months. The day my period was due I took a clear blue which told me "pregnant, 1-2". I was the happiest girl alive. Due to extremely bad stress off his family saying I should abort the child, a little while I began spotting, so I went to my gp and requested an early scan at the early pregnancy assessment clinic. My bloods were fine and got a scan a couple of days later. Expecting the worst we got there for the nurse to turn the screen around and point at a tiny little sac, she zoomed in further where you could see a small bean that was ever so slightly throbbing, this was our baby 😃 I never got along with his family but never let them bother me until they brought my child into it. After being emotionally abused I miscarried at 9 weeks whilst I was at work. I wanted space but never seemed to get it, instead I got told how the miscarriage was my own fault and there was no one else to blame, I left my partner a week after I miscarried and I felt so bad, it was his child too but he never stuck up for me, the next day after we split he slept with another girl, should I feel guilty for leaving him?
