I think my boyfriend not into me

So lately sometimes when me and my boyfriend have sex his dick will get soft during sex out of nowhere. In when I got into the shower the other day my boyfriend came in the bathroom as well but he was acting like he had to use the bathroom but when I opened the shower curtains he was watching porn playing with himself while I’m in the shower completely naked. So ladies tell me what y’all think?

Update: Ladies he tried to have sex with me after I caught him but I was completely turned off so I was acting like I wasn’t into the sex then he tried to have sex with me again like a hour later and his dick stayed hard the whole time.
