i need so damn help

so this guy i've been talking to for a couple of months hooked up with this girl. and i was rlly sad bc i rlly liked him and he sent an apology and like i was mad but i'm not ending things with him bc i believe in second chances and i rlly like him but i'm scared that he doesn't like me back like i'm afraid i'm going into this being like "i'm giving him a second chance" but like does he even wanna get back with me? how do i find that out? i was gonna get a friend to ask but should i just straight be like "i don't want us to be over, do you still want me?" or something like what do i say? how do i bring that up? i need honest advice even if it's harsh bc i know i'm being somewhat dumb for still wanting a guy who basically cheated on me
