I suggest something not a spell, but not non-magickal either. Create an empathic bond with him. He will feel your feelings and you will feel his. Not only does this practically guarantee he won't ever be tempted to cheat...if he ever is tempted you will KNOW it. It works in many different ways...and it's a wonderful bond to have with a lover. It will make both of you feel better when the other one is around, feel closer. It's also nice while you're apart because the bond does not go away and can't be stopped by distance. You will still have the sense of the other person even when they're not there.
Spells that 'make' someone 'do ' something that they would not normally do is not reccomended as they can have repercussions. He should be faithful thru your love not thru a spell. Is there a subtle reason you ask ? Relationships are always difficult things. Be the best partner you can be and remember ' Listen' to what your other half says.
If you are in a relationship, i suggest that you should not do any magick to the one you love. Nothing may harm you but it will show how "faithful" enough to use magick to him.
Men like to feel just as special as we ladies do, if they don't get that they seek it elsewhere just like us ladies do sometimes.
It's kind of hard to pull off sometimes, but the thing is not to be too paranoid or go to extremes which will only make him feel distanced and less compelled to be faithful.
Show your man appreciation, let him know that you still look forward to him, and show him you mean it.
Why would you want to cast a spell to keep a man faithful? If he remains faithful it is because he loves you and if he doesn't then hes not meant for you. If you cast a spell on him it's the magick that's working to keep him faithful not because he wants to.
Are you asking for this because he has shown signs that he might not be faithful, or is it just your own insecurities? If he has shown that he is not as devoted to the relationship as you its best that you let it go. If it is your own insecurities causing you to worry then perhaps an emotional healing, or even just a grounding of your energy would help.
Regardless, the best way to keep any guy is to keep him interested and show him you really care. Personally I would spend a day with him doing whatever he loves to do the most. That or you could wow him with your feminine charm ;)
