insecurity or gut/intuition? me f23 and boyfriend m26

Hi, so I have been in a relationship with this guy m26 since July 2025, everything started of good he was putting in efforts and all. due to being sick he had to go back home for 3 months making it ldr and it was difficult but we handled it. now we are living together, as he came back in march things have been pretty tough due to finances and we are both struggling especially him since he has never seen a phase like that. he has started doing uber a lot and comes home late and is not giving me the time that he used to . I feel like there is someone else or he is lying and meeting someone in the name of uber but there are not solid proofs.

also he does not text/ call me like he used to, but maybe its because he changed jobs and is quite difficult to use phone. but idk because sometimes he calls me at regular intervals and a lot of times he does not.

we had a big fight a couple days ago and I have never seen him that angry, he asked his friends to be with me so I can have someone to talk to and I got to know he is someone who does have a lot of anger issues and has gotten into a lot of physical fights but changed after meeting me- which is of course something new for me because I have always seen him as overly sweet person. more like a guy whose feminine energy is overpowering his masculine.

But again idk what's going on with me because this insecurity or whatever we call it has been eating me from inside and my mood is just not good anymore which is leading to more fights and the connection is not feeling the same anymore. Can it be any past trauma since in my last relationship I have been lied on, physically abused and body shamed/ bullied and left alone.

I am sorry if the grammar is incorrect or the paragraphs are not connecting; there is just a lot going on in my mind right now and idk what to do
