Kyle doesn’t want Amanda to do her own thing because he’s worried she’ll be more successful than him
Kyle constantly complains about how lazy Amanda is. I think it would kill him inside for her to have success while he hasn’t. As of 2022, Loverboy was $4M in debt. They lost $1.5M last year. This is not a successful company, and it doesn’t seem he’s ever going to recoup his initial investment. We all know Kyle has a massive ego, and he knows Amanda has talent, and I think he knows deep down that she could actually make something cool happen.
I don’t think it’s as much about him wanting control over her so she doesn’t leave, as it is him competing with her. Tbh I feel like Kyle secretly hopes that Amanda will leave him because he says he’s miserable in the relationship, but he doesn’t like being the ‘bad guy.’ So this is my theory :)
