I am an adult survivor of sexual child abuse and for me, I have very strong reactions to cheating whether they are real or imagined.
My best advice is to work on yourself and if you do decide to get into a relationship, try to know as much as you can about PTSD and the problems you may face together first. Be open-minded and honest with yourself and with your chosen partner.
It can be a rough and bumpy ride and it takes two people who are totally committed to one another to make things work, but even infidelity can be forgiven and trust rebuilt if you are really committed to the relationship.
As for jealousy...we all feel that sometimes, it is how you choose to deal with it that is the real issue.
I wish you the best,
