Girls, Should I be in a relationship with a hamster that said we will leave?

Hey everyone, recently for 2 months I have been talking to a guy. He is sweet passionate, protective, respect and honest. He seems to genuinely be a good guy. He has good values seems to respect women and have the same/ similar goals as me. Basically checkoff all the boxes for my dream guy. However once he told me he’s in a gang and his lifestyle at the moment he says he’s willing to change. He says he was raised in a bad neighbourhood and this is what caused him to be the way he is. He says by the time we start dating he will try and get a better place to possible raise a family. However I don't know how to feel. Feel free to comment and share advice on this background. For reference he took over the family business and he seems a genuine guy. For reference he’s 21 and I’m 19 im in collage studying business
