Give up or not?

I've known this guy for some months and we've hang out sometimes. We kissed. We are not officially dating but i really want to commit in a relationship because i've never dated someone before and i'm inexperience in relationship stuff. He has told me that he likes me before and yesterday i told him i love him. Here's the conversation:

Me: I love you
Him: is this like real love? What do you mean? Lol
Me : i'm serious
Him: why?
Me: No reason to explain it
Me: Don't you have the same feelings for me? Or am i thinking too much?
Him: I know I like you, you seem very sweet, but I am still very unsure about relationships and woman at this point, I know this is not what you want to hear but the truth is, over my last relationship, I'm still pretty much ****ed up over it.. I mean I've been working on finding myself spiritually and trying to find ways to let go but it's all still there like a wall of misery.. I'm sorry I know this is not what you want to hear but it's the truth
Me: I got it that's okay

I don't know what to do now. Lots of things came into my mind after reading his message. Here are the things that i've been thinking about.

First thought : it's okay if he is still over his ex and i can wait. He needs time to heal his wounds. And maybe i can just stay friend with him and try to make him relieve.

Second thought : am i wasting my time!? He is still over his ex and that means that i'm nothing for him. Why am i waiting for a guy who cannot love me back. And i know i will get hurt if he doesn't love me back after waiting for him.

My mind can't stop thinking. I can feel my heart beating so fast. I don't know what to do.. Should I give up or try my best ?
