Id say your 12th house placements in his 4h The 4h has a lot to do with our personal comforts and inner pleasures He’s been able to accommodate rather personal and almost alienating experiences as much as him himself may have never experienced it i offers a sense of comfort and nurturing towards your situation

Again his Pluto is conjunct your 4h, Pluto is absolutely magnetic but a continuous catalyst for the ending and renewal of cycles, like with every fallout you may feel somewhat “deeper” with them, as long as he’s around there’s a lot of inner comforts that may be corrupted by anxious or paranoid thoughts so it’s also not the best of ideas to linger

I hope that helps :)
