So I(16f) tend to notice that my bf(17m) tends to act childish when under a lot of stress or is tired. He tends to act clingy to me and use baby talk and choose his words in a childish manner when he's tired or stressed. He goes to toy stores to look at action figures and he even tells me that he wants me to come with him to do that on dates which is adorable at the same time, pretty sad. I found a post once that a lot of bpd people tend to age regress and from what i found from my research, bpd is caused by genetic and by environmental factors such as abuse or neglect. He was physically and psychologically abused by both parents. He is self aware that he does this because he had a bad childhood. Do you guys do this? Im just curious
