Is it natural to feel this way

I have been on good terms with a person prioritizing growth, trust and honesty. That person was not treated well in childhood and in previous relationships as well and now when she is feeling this kind of love for the first time and she feels resentment towards it. Is it natural to feel this kind of resentment ?

How can I contribute more towards changing this and changing the perception of love as chaos for a person who has been hurt all her life
