Is this your first
vape setup since (long ago) also I believe the site I saw selling it was fro $8.50 or something like that. It's less than a carton of cigarettes, seriously (I guess you could have paid more, depending on where you bought it).
But, investing in a decent starter setup you can
vape as well as the right types of liquid is kind of going to be essential.
The good news is, once you get that "ideal" setup (and if you are serious about things, a backup vape in case anything happens to yours) vaping can be as expensive as you make it. You don't need to spend hundreds of dollars on a new kit (and buying online can be cheaper, for sure) but you do need something reliable that you can actually vape.
I'm afraid that if my husband were to get "picky" about my saving my own life (I was nearing COPD and he didn't "have words" at all) and the "costs" of that... Well he was smart enough to see that I'm more useful to have around when not attached to an oxygen tank. Heh, ESPECIALLY if he's still a smoker, show him some of the shock/horror ads by "anti tobacco" organizations (why-quit is a great site for horror tales/pics about smoking and ask him if he'd like that for you.
Even more, I don't see how it's any of your boyfriend's business what vape you buy, if you are using your own money. If you are using his, I suppose that gets more complicated.
I regret zero "wasted pennies" I spent getting to a good vape for me, because it was surely less than the cost of my smoking (and health aliments). Man up, just a bit. I quit with a smoker in the house, but at least he wasn't "at me" about vaping, nor would I have allowed that as a) we are both grownups and b) it was my money etc.
My husband is now vaping himself although he's still dual using. I wasn't expecting that, remotely, but who knows, your BF may end up walking in your footsteps... PROVIDED you get equipment you can actually use successfully etc.
