HELP ME I'M A MESS!! :'( He likes me a lot, I thought I did too but now?!?!?!?

I dont want to be shallow or sound shallow. But there is this boy who is my ex boyfriend's best friend who likes me. I thought i liked him back but Im not really sure. I mean he is sweet he really really is and i like that it makes me feel special something that my ex barely did. BUT I dont think I like this boy 100% i mean I love the way he treats me i like his personality but his looks sort of make him not attractive to me. I mean I normally dont care about looks but this boy I do and I dont know why I do. I guess you can say I think I like him but I dont want to date him. 1) he is my exs bestfriend 2) he is sorta ugly But sweet 3) Im over my ex but its only been two weeks since we broke up ( we dated for 2 years n 4 months) and im not so sure im ready for another relationship 3) he deserves someone who loves him 100% and someone who can appreciate his sweetness and kindness, its not that i don't but I could date a boy who barely did anything to show love and not a boy who can!? I dont think its fair...

Well i thought i liked him so on sat when we finished texting i told him i luv u ( i know i made a big mistake leading him on like that when i wasnt sure of my feelings :() well yesterday he asked if i really did love him n I answered yes but as a friend, cuz i didnt think i liked him then like i didnt want him to ask me out! But i felt bad cuz i feel like i used him which was NEVER my intention I am not like that! I apologized and he said that it was ok that he would never hold a gridge against me n that it was him who should be sorry and I told him that it was not his fault that it was mine that I was soo confused at the moment and that when my head was clear I would explain everything! ( idk wat i meant by everything!!!) he said that it was ok n that i shouldnt beat myself up n to do it for him and he said that he loved me! well that made me feel worse!! I am not used to a boy being soo sweet to me! i think i like him but then at the next moment I think I don't! I am soo confused I feel terrible I have been crying cuz i REALLY REALLY didnt want to hurt and that's exatly wat i did i Really REALLY dont want to hurt him even more.

I cant make him wait until i clear my head cuz that may get his hopes up N if i eventually dont end up liking him well he'll get more hurt and I really dont want that!

If u dont think i should date him plz tell me how i should let him down easy so he wont get hurt cuz that is what i want to avoid. I dont want him to be hurt because of stupid me cuz he deserves way better than a girl who cant acept his feelings completly for some shallow reasons and for mixed feelings.... Plz help me I am a mess :'(

sorry for it being so long n I do know how to spell but I was rushing so I really did not put much thought to that.

THANK YOU IN ADVANCE
