missing boyfriend...wanting ex...

You're a typical girl who doesn't have the foggiest what she wants. Frankly I'm a bit tired of girls who are attracted to guys when they still have a boyfriend because all they do is feed the attraction and ask questions later. Sure some people will appear attractive, no doubt your boyfriend has felt attracted to other women. It's just that he probably doesn't act upon it.

Tell your boyfriend the truth about how you feel about your ex and see how he takes it. He's probably better off without you if you don't know what you want, because his thinking will be you should know what you want and thats him.

Your ex is an ex for a reason, and you're forgetting that. All the old problems will crop up again in time.

Yes, it's normal. You're remembering the good times only and comparing them to this relatively bad/boring time now. Think about all the bad times. And see your boyfriend more. If you haven't spent time together for over a month, I'm not surprised you're looking at other people.
