STUCK

so I'm having a really bad decision I'm currently dating my boyfriend of 2 years and hes my FIRST for everything but he has a cheated on me a couple times maybe 4-5 times and now he has a baby that's about to be 1 by his ex girlfriend that I absolutely hate with a passion and I know hate a is a strong word . but she didn't like me for no reason . and yeah I've gave him chance after chance and now this is the last so were more open to each other about everything we do ! I'm thinking about moving him into my apt in august but I'm confused because during our breakup I started talking to this guy and he's in boot camp hell be out in April and we've gained feelings for each other and STUCK because I like the both of them. But I don't wanna break any promises to the boy that's in boot camp caue I told him I'd always be there . and I don't wanna leave my bf of 2 yrs any ADVICe ladies 💔👀😔
