what is with my boyfriend (m19) wondering if i (f20) somehow manipulated him into loving me?

“did you groom me? is that why i love you so much?”

“you manipulated me into loving you”

“you did something to make me love you so much”

we’ve been seeing each other for 3 months now, and despite living an hour and a half from each other we see each other every day. this is also despite me working full time and him working half time. he tells me he loves me about 20 times throughout each day. that even changed to “i love you so much” about a month or so ago. he tells me a lot of the time that he thinks hes way too attached to me, doesnt deserve me, Needs me, hes terrified of me leaving him, etc.

if im correct (which i MIGHT not be but i believe this is right), he started questioning if i manipulated him into liking me after i tried something in bed.

im the dominant one in our relationship, and sex for us (before this) usually went by me degrading him and him worshipping me. one day i was kind of “giving him the controller” more, i was basically talking to him like a mother if that makes any sense💀😭(we have both established this as something we’re both into, LEGALLY). he was very into it but eventually he kind of freaked out about not knowing what he wants / not knowing what to do with “control” over the situation, since this was i guess the first time i was asking him what he thought would feel better for him and such. i tried explaining to him what i was doing, the best word i could find for it at the time was “grooming”😭😭😭 and he was really shocked but also really liked that. he would ask me basically everyday after that to “groom him”, which just meant what i did in bed that time.

IMMEDIATELY after we were done that day he asked if i had groomed him 😭.. we met when i was 19 and he was 18. no i did not groom him. he also never really understood the proper definition of grooming, so he had a psychotic break this month and one of his delusions was that everyone thought he was a groomer, when he would describe how he “groomed” someone it was someone of the same age as him that he made consensual advances on. hes had this fixation on “grooming” ever since this sexual encounter of ours.

he would recall times he believed he was groomed (some were Definitely grooming, some were just people showing interest in him), as his psychosis was developing he would recall how he was accused of grooming in a psychward he was in when he was 17 (it was a misunderstanding and the man that transferred him said this happened a lot), and an entire sa situation he was subjected to at 15 completely resurfaced and he was VERY fixated on his assaulter. he had a delusion that his assaulter and his gf were running an experiment on him.

aside from all of this, we first met on a video game, and HE was the first to make advances on me. i was actually turning him down for a while because i was extremely scared of commitment at that time. he would later tell me he just wanted to get in my pants when he first met me too so with this in mind it makes it even more ironic that he believes i manipulated him into loving me😭

thats about all the helpful details i can think of to figure out why he questions this, lmk if i need to add anything that would be more helpful
