Thanks in advance

ok well my exs best friend likes me. my ex n I broke up two week ago after dating for 2 years and 4 months.well so my exs best friend had told me he likes me while I was still dating my ex almost two months b4 we broke up.well at that time I was still dating my ex so I told him it was sweet but that I didn't return his feelings. Its been two weeks since the break up. I'm OVER my ex.well but his friend has been really sweet with me he has always been like that to me, he is really sweet. since tuesday i thought liked him but so sat i was texting him n well then i told him I luv u but i sorta meant it as a friendly gesture cuz i would usually say that to my friends. im not sure if i like him. i mean i thought i did but im not sure. well today he asked if i really did love him answered yes but like a friend but then i felt bad cuz i feel like i used him. Although that was NEVER my intention I am not like that. I apologized after wards I told him how im really confused how i felt terrible for not returning his feeling n he said it was ok that he would never hold a grudge against me and that he loved me!well that made me feel worse! i hav been crying cuz i don't know wat to do i mean at one moment i think I like him at the other i don't!! after the break up with my ex I wanted a month free of "boy trouble" but somehow I have managed to get more than i usually get.well I thought I like him he is REALLY REALLY sweet. he makes me feel special. my ex never throughout the 2 years we dated ever told me he loved me he barely made me feel loved. but this boy does but i don't believe I like him a 100% n i don't think its fair to date him if I don't like him completely. and i don't want to rush things just in case I really never do.

1) well I sorta made myself not feel anything towards him cuz he is my ex best friend an I don't think I would

like my ex to date one of my best friends so if I don't want him to do that what right do I have to do it to him?

2) sometimes I feel like I like him but other days I don't, I think that its cuz well he really isn't that attractive but he surely is sweet.I don't want to be shallow but I don't know I think that sorta makes me not like him much but at the same time I do!!!

3) I don't think I like him 100% n I don't think its fair to date him if I don't like him 100%

I don't really think I deserve him he deserves someone better than me someone who can return and appreciated his feelings it isn't that I don't but I could I accept the feelings of my ex who well never told me a single love word n not of the boy who does!

I told him that right now was so confused n that when my mind was cleared I would explain everything ( but what is everything!?) n that I was sorry n he said that it was ok but to please not beat myself up bcuz of it n to do it for him...

n i don't want him to wait until my head is all cleared cuz that may get his hopes up n if I don't end up liking him he might get more hurt than now n I really really don't wanna hurt him!

what should I do?!

if u don't believe I should date him how should I let him down easy so I don't hurt him!?

I REALLY REALLY don't want to hurt him!

Oh and sorry I do know how to spell but I was rushing so I really didn't put much thought to it.
