I'm not sure whats going on anymore. I don't agree you should get rid of it as when I was about his age, I dove in head first and bought a hatchling Nile Monitor off a breeder I knew and he grew into a giant puppy which Niles aren't known for. I did rehome him though as he simply outgrew what I could offer him. I didn't have the resources to build him a 10x5 cage.
The OP needs to read up on the snake and realize that a burm is going to be a big commitment. And the bigger it gets, the harder it is going to be to rehome it as most people wants baby snakes, not a huge 13' snake off the bat.
And if your reason to try and find a girlfriend is for someone to help you handle the snake, then I don't know what to say. My reasons for wanting a girlfriend at 19 sure weren't to help handle my monitor....or at least I didn't call it that but we'll leave it that as this is a family friendly board lol.
Bottom line is OP, you need to take a real hard look at if you will be able to financially and physically take care of a snake that will grow to at least 12'. If you have any doubts, best to rehome now while its a baby and just find a 'pet' girlfriend. They require more financially and physically but they do thing your snake cant and they don't require being fed a 5lb rabbit every weekGood luck.
