hi there, you seem to understand the situation and what you are asking so i wont give you the "love spell talk".
I think that divination might help you see what he thinks of you, where your relationsip is heading, it is only natural for couples to have small troubles and arguments from time to time. and usually there are other things that spark these troubles such as work, school, parents, or just a bad day.
Now as for a spell, write his name on a paper burn it in the flame of a white candle while chanting a spell.
so i may no longer in doubt dwell,
i cast this truthful spell..
"what lies within,
now let me see,
his true feelings,
reveal to me."
*i just made that up...boy i am on a roll today (or maybe i heard it somewhere:P)
