We must always reflect on the long time of (what I, as outsider, might call highly questionable) interactions within Christine's family: With other singles, above all her mother, apparently not following their own high standards, while Christine was openly portrayed negatively.
If I try to imagine that:
- Other family members with same relationship situation, but not belted, not living chastely, even randomly sexing around, ...
- while I - being convinced I could actually live chastely (whether a delusion or for real is different topic) - were the one put under pressure to wear and were made to look silly (about my past, my attitude, or whatever) in front of the above same family members for months and years.
I think resentment was a rather logical consequence. And it might take long and considerable steps to improve the overall situation.
