I'm very sorry to hear about your first pregnancy; nobody should have to go through what you have been through.
To (try to) answer your question, I think we need to know a bit more about what happened to you before and after the abruption. Did the doctors do any sort of blood test screening? Was your blood pressure abnormal? Was your baby's birthweight much smaller than expected? Did they do any tests on the placenta?
What sort of surgery did you have to remove the fibroids? Were the inside, within, or outside the wall of your uterus? Were they treated by open surgery or by hysteroscopy (camera into your womb through the cervix)?
Having fibroid surgery that involves cutting through the wall of your womb (as opposed to just cutting one off a stalk) would increase your risk of uterine
rupture should you go through a labour. But it shouldn't increase your risk of spontaneous placental abruption by any meaningful amount.
Abruption results from bleeding between the placenta and its site of attachment to the uterus. This may be after trauma to the abdomen (as in the first reply post), or "out of nowhere". There are a few conditions which are associated with an increased risk of spontaneous abruption, like clotting disorders, some medical disorders (e.g. hypertension), and something called antiphospholipid syndrome (APLS).
Some of these conditions can be treated to
minimise your risk of a placental abruption happening again. If no cause or association can be found, this is not necessarily a bad thing. It would mean that the risk of another abruption is low, but you should still be managed as a high-risk pregnancy just based on your history.
The management of your pregnancy will be more intensive than usual, and you'd be best served by an elective repeat caesarean section, somewhere around 37 weeks, depending on the progress of your pregnancy.
I think the best thing for you to do would be to have a visit with an obstetrician (preferably the one who managed your last pregnancy, if possible)
before you fall pregnant, to see if any investigations need to be done to optimise your chance of success in your next pregnancy.
It's natural to not want to have anything to do with the treating team or hospital after a bad outcome. Even if nobody is at fault, sometimes seeing familiar faces or places can just be too hard to bear. But remember, these people have the full medical record of what happened in your last pregnancy, and I think this can be advantageous.
If you happen to know the answer to any the questions I asked above, I can try to answer your question a bit better. But, eitherway, I wish you the very best in your next pregnancy.
