Hmmm... I mean, its good 2 care for somebody else. Cuttin off a relationship is hard for most ppl. I understand that u dont wanna hurt his feelings, and I know u dont wanna cause problems. But a negative overreacton might be inevitable. U have to look out 4 urself 2. Try to prepare and anticipate the possible outcomes of wut might happen when that time comes. Its a good idea 2 be polite when u do so, but the hardest part is when u actually deliver the news to him. Then, u will get that off ur chest and release thAt burden. After that, its a matter of overcoming that feeling of wut seems like guilt, and finally moving on with ur life. He may be hurt in the process, but he also will have 2 except it. U dont have 2 blame urself, it seems like u tried everything in ur power 2 make it work. But staying in a relationship no love,communication, or understanding will only harm urself even further, u feel me? U must look deep within yourself and find the courage to follow through with ur plans. I wish u luck!
