For starters they have been broken up since 2020 but remained off/on for a year or so. We started dating 2023 and have an amazing relationship, very loving.

She was an alcoholic and abusive. He was able to get funded therapy for it as there were police report. His trauma goes much deeper including childhood s a, child neglect, grief, etc.

Of course I want him to get the help he needs and support him. But part of me is so anxious because I know he’s talking about her and she clearly had this huge affect on him. I don’t know what exactly it is that makes me worry. Like I know he loves me, tells me I’m the love of his life, all that. Why does this bother me so much? What am I afraid of? And how do I deal with these fears? I have a hard time understanding how he could be so in love with me and be so affected by this other person still?

TLdr; how do I deal and cope with anxiety I feel over my bf being in therapy over abusive alcoholic ex gf and learn to trust the love he has for me despite him being so affected by his past?
