Will hating him make me feel better?

This is kinda long but please be read and give mature responses. Thank you.

Well I told my ex my feelings last week and he said he needed to think about it(we had lots of complications) and he gave me his answer on Thursday and said that he does not want to be in a relationship right now and being friends the best we can have and he said maybe in the we future we can. I told him No, its pointless saying in the future because I won’t give in. I told him I don’t want to be a relationship myself, I have a lot of things going on in my head and he asked what I wanted. I said I just wanted us to start dating again and go slow, real slow. He seemed interested because he admitted that he likes me still and has feelings for me and will always will, but I told him if we’re going back to dating, I just want it to be me and you like last time. He is talking to some girls(getting to know them) and he said he just can’t let that go(he wants to keep his options open). I told him I’m talking to guys too, but I just don’t feel it with them. We wanted to continue our conversation but not that night because we were both confuse. He asked if we can talk in person, but I couldn’t talk to him that friday and he couldn’t talk to me on saturday(work) and he asked if he can talk to me this coming saturday and I said no. I am not going to wait around for an entire week for him to make up his mind when its just going to hurt me. He said if he can call me tomorrow and I didn’t respond and he was like “just say yes” and I just said bye. I texted him the next day, asking him to meet me for a late lunch and if he cannot then I told him to not call me tonight. I said I am satisfied knowing that we commonly care for each other and I will always care for him and if he needed a friend to talk to don’t be shy. We both know that this “Me and you try again” will never be in future conversations. He texted me back saying He couldn’t meet me for lunch, he had a lot of things to do but he’s still going to call…” He hasn’t and I am not waiting. My friends told me to hate him because of the way he’s acting but I can’t seem to, because I feel that’s too immature. I like being civil with people, especially someone you care about. I guess I’m too nice to hate someone. I don’t plan on calling him anytime soon or text him or answer his call. Until all my feelings go away and we actually can be friends. Do you think hating him will help me feel better? I actually regret telling him my feelings because I think if I just ignored them then he wouldn’t have the upper hand and they will soon fade away but then again I feel better because I am true to myself and I am honest and did not let those feelings eat me inside. I guess its hard for me to hate him because I appreciated that he didn’t lead me on and talked to the other girls while going out with me. Any thoughts?

I’m 22 and he’s 19(I feel like he’s still young and does not know what he want and is in his player days) I know he still likes me a lot because he is very attracted to me and always wanted to know what I am up to during the weekends. We hanged out a lot before(not intimately).
