Is it just my mental issues or am I really being tricked

This 1 guy I've been talking to for several months and am now sort of intimate with, now keeps sending me snips of conversation with these other girls we both know. And these girls are trying to seduce him in these texts. He asks me what I should do about it. We're not committed yet so I tell him it's on him. I asked him if it is not consensual and makes him uncomfortable he should be firm with them because it counts as hara.ssment. Stuff like that. But here's the catch. He never shows me the texts HE sends them. If I ask for context he doesn't respond or says "she just randomly started texting me this", to which I try to help him with a response, as he literally asks me what he should say. But then he ends up not saying it. I ask him well then what DID you say? But he never responds.. Or says something but doesn't send a snippet like he does with the women's messages. He never shows me the full conversation. Just snippets that apparently show how badly those women want him. That just sounds sus to me. But what if he's not lying? I don't want to accuse an alleged victim of se.xual harassment that they're responsible for this. But then again I have serious trust issues because men have not been loyal to the women of my family. But then that also makes me feel I'm probably thinking too much based on my past trauma. But then again what if it's a real gut feeling that in dismissing as over thinking? But then again what I'm I'm victim blaming?
Ugh. I don't know.
