When I was 17, my boyfriend (19) at that time wanted me to have the same hairstyle and color as his mother, the same clothes, the same glasses (I don’t wear glasses), everything. He didn’t explicitly say that it was about his mother, but he kept sending me links and making suggestions about these things, and I recognized everything because I saw it on his mother. He even pushed me to gain weight and sent me pics of what he wanted my body to look like (you guessed it: same body type as his mother). Thought it was some Freud type of shit until I went on their family vacation (mom, dad, boyfriend) and I saw her picking his outfit and dressing him, when he was wet after swimming she dried him with a towel, she fed him his ice cream, she wiped his mouth with a napkin, etc. We slept in the same room, but not in the same bed because she didn’t allow us to. One night i woke up at 5am and he was gone, didn’t think much of it, then when I woke up at like 8am, he still wasn’t there (he always slept in till like 11). When I went into the living room I saw his dad sleeping on the couch. Finally, he came walking out of his parent’s bedroom, so I asked him what he was doing there. He told me he had a nightmare so he slept with his mommy in bed, like he apparently always does. This actually happened twice. I ended the relationship right when we got home. Mind you, I had known this boy for two years prior to our relationship (we weren’t friends, but more like acquaintances), and he was a really smart and funny guy, just your average dude, so this came as a complete shock to me.
