I would strongly suggest starting with a monitor that is easier to deal with, very few niles become tame and most won't even tolerate you being near them (mine won't) they require huge enclosures with a large pool and require a lot of care cleaning e.t.c and have heavy heating requirements they have an extremely powerful bite that could possible relieve you of a few fingers or do serious nerve damage that is off the initial bite then there is the possibility of secondary infection.. I am not trying to scare you off keeping them but am just saying don't run before you can walk. Picture a 7ft lizard rushing towards you and before you have even had time to think it's got your hand,arm or possibly face I am not saying that would definately happen put it is a possibility i find my niles behaviour very erratic and that is what can make them dangerous there sheer unpredictability you never know what they are going to do. That said for how unpredictable mine is i would not be without it but i would never have dreampt of having one for my first second or even third monitor and if researched properley i am sure your boyfriend will realize that it isn't really a suitable first choice. Try and find someone in your area with a large one or even ask the petshop whether your boyfriend can clean theres out and see if he still wants one knowing this has to be done on a daily basis and most of them found in pet shops are generally more subdued because of stress than they are after a few weeks of being in your home. Finally for what it's worth i would say do not get one
