Hard to answer, not much info ie how old are you, was this physical abuse, and dysfunctional family, alcoholism, divorce?? I can tell you that I felt like my upbringing was pretty bad, but lots of others had it much worse I'm sure. But, when it comes down to it, family is all you have in the world and families usually put the past aside and move on, hoping it will be better. If you've distanced yourself from your parents or siblings, maybe start reaching out to them now as an adult by phoning them once a month or something. I think just by doing this and talking about normal things like your job and home and how's it going with you etc.. you will find healing and forgiveness, and you will begin to feel like an adult that people respect, you'll have more confidence, and your relationship with your fiance should improve. You've probably heard of skeletons in the closet, well this is just what I'm talking about. All families have them, but they carry on with their lives, ignoring the past, and when thanksgiving or christmas rolls around, they all get together and pretend they all love each other and get drunk and start fighting about old animosities...oh wait that's what my family does lol. But I hope you try that, phone home, stay in touch, try to be part of something (a family).
