User blog comment:Animecrazy036/Who will Erza marry?/@comment-7418318-20130509072237

What does an age difference of a year or two matter for marriage?

Also Remember the reason why Jellal pulled back at the last moment. He didn't do it because he didn't want to. He did it because he thinks he doesn't deserve such happyness (yet).

If they can convince him that there no longer is any need for self-punishment, I'm sure he'll jump at the chance to get together with Erza.
