Is it normal to want your ex-boyfriend back?

My ex-boyfriend just broke up with me a few days ago after a few months of dating. He said that we never had a relationship and that it was friendship. That I wasn't there for him when he needed me to be. He said he needs someone who hide or isn't ashamed to be with him.

We met at work and he was unlike anyone I had ever been interested in. He has tattoos, he's been married twice, he has two children. I'm a virgin thats never been in a relationship. He's 33 and I'm 25. I'm more educated than he is and make more money. He's 5'7 and I'm four inches taller. He's Puerto Rican and I'm Black...he was just different but he was the first guy I ever loved.

A few weeks ago he stopped answering my calls and texts...didn't speak to me for a good three weeks! Finally he called me at work and basically broke up with me. But wanted to remain friends...he said with everything he's going through he doesn't have time to be in a relationship and that it's too late for me to be there for him now.

I was so hurt I took the day off of work the next day and spent it in bed crying.

I asked if there was someone else...he wouldn't answer. He asked if this was because he didn't love me anymore and he said it had nothing to do with that...that no one said that.

I saw him yesterday and after talking for a bit he looked me up and down...idk what that means.

Looking back on it now I was way too guarded. I think my attitude got in the way, I wear as a shield and I think it makes it harder for people to look past that and get to know me. He treated me so well and I was just so mean and closed off.

I miss him already and I think want him back. Do you think later we could ever be together again? How can I work towards that? Or should I just take this as a learning experience?

Also, am I doomed to spend the rest of my life alone?
