I Still Want Him 😩

So there's this guy I like, DJ for short. He's great!! He motivates me to do things that need to get done like studying for the ASVAB, and my permit/license tests, maintaining control when saving my money, just everything. He takes me out on cute little dates like the Cheesecake Factory, one day after work he took me to the airport to watch the planes land and take off, he's teaching me how to drive & he lets NO ONE but his mom drive his car talking about "I must be special," 🙄😏 yeah yeah whatever but he's so sweet. He's 24 and I'm 21 but I don't mind the age gap. I know you're thinking so what's the problem, right? To me there wasn't any problem but APPARENTLY my child's father is "besties" with DJ's brother. They used the term "best friend" to try to make me feel guilty but THESE GUYS ARE NOT BEST FRIENDS they barely talk. And at first I felt like it had nothing to do with my child's father because we are not together. Of course he threw a hissy fit when he found out, but I can't leave DJ alone for some reason. I feel like he's good for me. So what I really wanna know is am I wrong for liking his "friend's" brother? 🤔
