Am I just unlovable...?

Although a certain ex-boyfriend of mine told me he loved me while he was with me, he told me sometime after we broke up that he’s never truly loved any girl. He also told another girlfriend of his after me that he didn’t feel anything for me.

In anger, another ex-boyfriend of mine told me while he was with me that he guesses he convinced himself he loved me, but he didn’t really.

Another ex-boyfriend of mine ended up breaking up with me and telling me that he wasn’t being completely honest about loving me.

The guy I like now only loves me as a friend…

I could go on, but basically this doesn’t really make me feel that great. Am I doing something wrong? Am I not worth falling in love with? And why have I been told I was loved if it was a lie?
