I would say be careful what you wish for, you stated you are not that good with spells,casting a spell requires you to know your basics, it could backfire on you.
Might i suggest sitting down and talking through your problems, it may not be you thats making him unhappy it could be a number of things stress related to work,money worries ect.
It could be solved without using magic ,spells are not always the answer.
Hope things work out for you.
