HELP IM LOSING IT !

okay so story time ...

So , it all started when my boyfriend was looking at pictures of my mother on facebook i found it kinda weird ... but i didn't say anything he then started texting her more often over time behind my back. fast forward 3 months or so come to find out i now have a step brother on the way , but she didn't wanna tell us who the father during all of this my boyfriend started going out more than usual and acting weird ' he didn't wanna have sex with me anymore he even rejected my blowjobs !

we started arguing more and more. one day he told me he was gonna go to work ' i went to go visit my mom and his car WAS THERE , i went inside and heard moaning ( very scarring ) in the heat of the moment i went to the hidden gun safe and took out a M4 and headed straight to the room. GIRL let me tell you ' i was this close to shooting him. after arguing back and forth he grabbed the gun while my hand was on the trigger and it accidentally fired and shot the family dog.

i rushed to the dog and i started crying. i grabbed the closest thing to me ( a lamp ) and threw it at him. after all that we just argued and i went home. he then came to my house apologizing to me saying everything is fine and the dog was ok. "lie". he then told me he was leaving me and didn't want anything to do with me and started blaming me and that it was my fault because i didn't give him enough attention. he then proceeded to tell me he loved my mother and that they were gonna disappear cause they didn't want anything to do with me. So i stabbed him with a pencil in the neck because i was furious of how he felt for her. he started bleeding and bleeding and i instantly felt regret. but why? after all that why should i feel anything for him. eventually he bled out and i left him there.

and THEN i woke up. 🥴

should i tell him about my dream or no? after all it was only just a dream.
