which is better?

is it better to protect my feelings or the feelings of someone I love? and i can't protect both....i already tried

It kind of depends on the situation, and the consequences that might come from it. Since you didn't say the problem, this one is kind of hard to answer. Sorry...lol.

ok here is the situation....So i really like this guy (we went out but then broke up...thats a long story)who used to hate me. and when he hated me all i wanted was to be friends with him. now that we r friends it is wicked painful for me to be around him knowing that all we will be is friends. so my choices r to get my heart broken more and more each day (staying friends with him) or i can stop being his friend but he only has 2 real close friends(i am one of them) There is also another reason some people think I shouldn't be friends with him but if you wanna know that reason ask me cuz i it is long. I really want to stay his friend but it is killing me, so please tell me whether i should be his friend or whether i should protect myself.

It's not the question of which is "better", it's which shall benefit the cause in a greater value/create the larger impact

and it definetly depends on the situation, but generally it is the selfless, and overall right and possibly obligated, thing to do to put others in front of your own desires.

Alright, I just read the situation and, I definetly think his feelings are just in protecting more than your own, and you just need to get over yourself.

Time heals all wounds (though you might not think so) and you shall find in that due time that this "pain" you feel when around him shall fade and you will fancy yourself with another.
and so on, so on, so on...

Anyway, considering the guy only has two close friends, I think his state is more important than your difficulty in coping with your lost relationship. So my advice: get over it and stick with him.

i think you could explain the other reason in a few sentences: try

ok so a trusted adult knows the situation and he says the guy is just trying to bring me down with him. Casey(the guy) is suicidal and the adult thinks he is just doing it to bring me and his other friend down....so i am afraid if i am not his friend he will commit suicide cuz he will only have one friend left

Well obviously if the guy has that many issues (being suicidal or most likely faking it) he needs a friend more than you need to get away from past memories.

even if he is faking it, just goes to show how much he's going through that he feels he needs to do something as pathetic as that to get attention.

I would elaborate on how to deal with an attention-seeking faker, but that's not the subject here.

I still say stick with it.
