Is it normal or okay to take my ex back?

I think its not normal or common to take your ex back but at the same time, why not? I understand if they did something unforgivable or just hurt you or you have completely moved on with your life. But if you're not taking him or her back because you think it's wrong to do so, then I don't think that's a good thing in my perspective. In my case, it's really iffy. He broke up with me but Im not sure if its because he didn't wanna be with me or his excuses were actual reasons why it couldn't work with us. His reasons are valid but I was willing to work through them where he wasn't so something in me tells me it was more than our circumstances, it had something to do with me. However, something else tells me that he truly enjoyed being with me and hes missing me right now just like Im missing him. There won't be another girl who will make him feel like I did, he even said its rare how good I made him feel. And I believe him cause what we had was special just like anyone who's really in love. No one has made me feel like he did for sure and I dont think there will be another one to be honest. Although he left me, I think I would still be willing to take him back because I love him and I feel like we're meant to be. Does that make me look weak? Sometimes though, yes my pride gets to me and says "why are you gonna take him back? he left you, his loss, screw him." It does feel good to make him realize what he had but is it really worth it? I think its way more worth it to take him back and possibly look weak cause i know how I really feel.
