"Believe It" is a melodramatic plea for trust and forgiveness in a relationship, with a dash of ego and power dynamics thrown in for good measure. The singer is essentially saying, "Hey babe, I might have messed up in the past, but can we just forget about that? Also, if you leave me, I'll be as good as dead." There's also an undercurrent of insecurity here - he's worried she'll reject his proposal or embarrass him. He acknowledges her power (both generally and sexually), but also seems to resent it a bit. Meanwhile, he's dealing with trust issues on his side too - he loves her but doesn't fully trust her. And let's not forget the family drama - his mom is already video calling her! So basically, it's your typical modern love story: complicated, messy and full of mixed signals.
