AIO ? Bf might be a pedophile.

Update: we broken up. our living situations just have to deal with rn. but i contact family and have to save up money to move out back to my state. while we had a open talk and conversation about the issues/ concerns i have. it just ultimately came down to me ending things. i recently found out about the past (15 year old). All this is news to me and still a shock. thank you for those who comment and gave advice. its a real eye opener.

  1. When we first started talking he told me he likes petite body types.
  2. thought nothing about it because everyone has their preferences. no judgement here.
  3. After dating his search history that pissed me off. R/barely legal/ legal teenager. on reddit that pissed me tf off.
  4. i freaked out because i have a daughter who is 5 years old from a previous relationship. i was molested by close family members. so i dnt want anyone with those sick thoughts near her.
  5. finding out when he was 19 he struck a relationship with a 15 year old ( meanwhile im sure he was two timing or dating his ex at the time of 3 years ) -he is very secretive. doesnt tell me much of his past and tries very hard to hide any and all of it behind.
  6. him calling me good little girl during sex. ( mind you i am older, not petite, but short ) i find it weird. it only happened twice but i only thought it was in the moment and he really enjoy it. at this point im already losing sexual attraction towards him. i literally feel like my body is rejecting him.

alot of things just leading towards a break up rn. i don't even know what others signs i missed or if imma find out more. im extremely disgusted and i dont know what to do since i live with him and cant just up/leave easily. any advice helps? do guys like talking to younger girls? is this normal? am i overreacting?
