I need help (new guy)

So I started talking to this guy through snap chat and We've been talking for a week , And around the third day he started talking about how he's in love with me and wants to be in a relationship with me and etc.. he lives in ny and I'm from nj , he doesn't have a car so he would get here by train and bus. Is this relationship worth it , even for fun? I'm a virgin and he knows ,and plans on having sex ....We are also both adults btw
