You can't. Believe me I tried this one when I wanted to end it with my ex, after about 6 months of being a complete bitch I realised that it wasn't working!
Your just gonna have to be honest with him and tell him that you don't wanna be with him anymore, it will hurt like hell, you'll cry, he'll cry, but it'll be worth it for both of you in the end.
Oh dear, don't be such a coward - the least the poor bloke deserves is honesty! Whether you "make him fall out of love with you", or face up to him and tell him the truth, you'll know it was your decision at the end of the day.
Whatever you do, don't try and be friends. Unless you break up on completely mutal terms, I think a definate separation is really important. There is no 'reasoning' with someone if they're in love with you, so it's not worth debating about it.
I wish there was a button in this world to do just that. To turn off love towards someone as it would save alot of heart ache. Just sit down and tell your bf straight, it will hurt, there may be things said in the heat of the moment but you cannot act like a bitch to make him fall out of love so he will dump you, so you feel less guilty, this is almost like a cowards way out. Tell him straight. Sit him down and be civil to him, not bitchy, not picking fights etc.
Dont even try. Thats too long a game to play. If you cared enough about him to have a relationship or friendhsip with him in the first place, then respect him enough to be completely honest with him if your feelings for him have changed. That way you move on faster, your karma is better for being as honest (while being as kind as possible). He may hurt but you wont have added to it by being a *itch in the process and you will honestly feel better in the long run about the way you handled it. xx
