LADIES PLEASE ADVISE ME

So basically there’s this boy that use I was dating kinda months ago and these past two months we’ve been talking again more in school like more flirty as he broke up with his girlfriend however I had a boyfriend

Let’s call this boyfriend jack,jack was basically my rebound from this boy let’s call him sam , jack was my rebound from sam but I caught some feelings,jack is so nice and carigg and he says everything a girl wants to hear but he just kicks off all the time and tries to flirt with my friends and doesn’t tell girls to fuck off if they try and touch him however hes protective and we can talk about anything

Sam is and was a fuckboy,he cheated on his girlfriend with me,however I see him everyday and he makes me laugh and happy and I feel so confortable around him I can say things how i want to and I don’t have to stress about what I say and he satisfys my Needs and he actually has ambition and passion you know?like he’s so like excited for his future not like jack jack just wants to smoke weed all day.

Sam said that he doesn’t want me to choose him as my second choice and I said but I’m your second choice so why can’t you be mine and he was saying how he wants me to be his first and I was saying that I want to but if he cheated on his girl with me he will deffo cheat on me and he was having a go at me saying he wouldn’t even think about doing that that I’m so different compared to her and shit like that but idk what to believe cause I think he just wants sex tbh
