About a hundred years ago I had a retail reptile store. After we had been around for a while there was one scenario that had repeatedly played out the same way. Mostly it was guys, but sometimes it was girls.
Here's how it went.
Hey there Mr. Shopkeeper, I know I've had this snake, or these snakes, depending, for a while (sometimes years), but I've met someone I want to spend the rest of my life with and they're afraid of/don't like/don't understand/can't stand etc. my snakes so I've got to give them up. Will you take them off my hands and give them a good home?
Depending on the person and the reptiles they were trying to move on, we often aquired previously owned reptiles. Then, generally 3 to 6 months later that same person would come in and want their reptile or reptiles back because they had broken up with the love of their life.
Seriously, this happened often enough that I remember it 20 years later.
Don't do it. If he loves you, he'll adapt. If he can't adapt, does he really love you?
