If it were me, personally, I'd go for it. Whether you wind up keeping him in the end or not. But that's just me as I get extremely attached to horses.
I own two currently, I've been halfways looking for a third for a while now and haven't actually wound up getting anything. Eventually I'll have another, or two, or three. Two is my minimum. I have a leaser for my youngest mare right now for a couple days a week, and not because of cost. Right now I simply don't have the time to bring her along 5-6 days a week and show her like she deserves. Some weeks I can, some I can't, so thankfully my leaser is very flexible in her days and willing to do less days some weeks so I can ride more if I'd like.
I have a lot on my plate, and will have even more in the fall, so an understanding boyfriend really helps on my end
Somehow I find the time to be at the barn 7 days per week - sometimes twice per day. I try to ride at least 3 days per week in fall/winter, and 5-7 in spring/summer.
