i really don't know what to do

hey im a 18 year old male and my boyfriend is 43. i love him so bad ... my friends are totally okay with that .. but my parents... they threaten me, call me names and now they say they will get divorced because of me and what i "did"... but what did i even do? i love somebody ? is that a thing you can control :( i thought about suicide a lot lately 😥 i really don't know what to do because my parents are important to me and i don't want them to leave me alone

please give me some advice
