penkitten..i am sure your bf had more things than just creatine that made him fat (like lack of sex.. hahahaha
)
I've been taking creatine for a month and a half now.
Some things i've learned over time:
You can take creatine with water, but apparently it doesnt work as well as if you take it with juice. (after the work out).
Loading isnt necessary.. take 5g one hour before working out, 5g one hour afterwards.
Drink at least a gallon of water a day. this is very improtant. YOu dont want to dehydrate. I find that if i dont drink enough water, my lips becomes chapped much easier. (easiest way to drink that much water is simply to have a liter water bottle next to you when you watch tv/on computer.. you drink and dont even notice)
Peeing 20 times a day is normal when you drink that much water
As for results, i am not quite sure, recently i've reached a pretty impressive goal for myself - 135 on incline, never even considered it, and bam! all os the sudden pulled 2 sets of 6 each. If that was creatine helping, more power to it.
So far im taking it with water only.
