/feels/ - Advice & Venting

back in dec 24, i found some messages on my bfs phone from a sex worker on reddit that he sought out. the way the messages were made it seem like it wasnt the first time he had done something like this, so since then i had been suspicious that maybe this was a constant thing for him.
i then found through an apple payment that he paid someone for something on of, but i couldnt get into his account, until today.
i finally got in his account and saw he was subscribed to multiple workers and also was talking to them. ik obviously for them, thats literally their job, to talk to people, but the way some of the conversations went made me feel hurt.
i want to also add that, as long as it isnt an addiction, i dont care if he watches porn, i do too. my problem is the fact he is paying a lot of money for it and the conversations hes had with some of them talking about his interests, recommending them music, etc. stuff that feels personal.
i feel like its borderline cheating, but at the same time i dont know. i’ve never been in a situation like this and don’t really know how to feel nor what to do. it just also sucks because lately things between us have been stagnant and stressful, just from things happening to us separately, it isnt helping us be our full selfs atm, so adding this really makes everything feel even worse.
he told me he wants to be with me, and i want to work it out, but at what cost?
