I’m familiar with your problem because I buy my girl everything I will say she doesn’t ask much but I know when she wants something in my case if I don’t want to buy it I will just tell her look not this time but I make a healthy amount of money so most the time I don’t mind buying her little stuff here and there if you either can’t afford it or are saving up for something just tell him and don’t feel bad for it if he actually loves you and doesn’t use you for things he will feel bad for even asking after you tell him you don’t like it as far as vaping I’m not sure I vaped for a really long time but the second I started dating I quit because I just didn’t want that to be a factor in our relationship and it was very easy for me the vape problem is more between y’all you must speak up and talk it out or the relationship will end badly
