Well, If he looks at you the same way he did when you were together! OR If he talks to you and sorta looks away and stumbles on his words. (nervous) OR
Also maybe he isn't shy and its just you!!! If he always stares at you. If he tries to talk to you or you catch him talking about you.
you can't unless you ask him
In this case you should be honest, tell your ex that you still have feelings for him. But, im going to be honest, don't let your current boyfriend find out about it. Tell your ex boyfriend that you still have feelings for him and you know its wrong because you are both dating other people. But mention that you havent yet moved on. & when you admitt you still have feelings for him, reminisce about the things that happened between the two of you.
if he talks about her alot and if he compares her to you
if he is acting the way he did when you were his girlfriend and if he is haning out with you a lot and flirting with you.
To find this out you hang out with the girl to see if you still have feelings for her. That will give you your true feelings about her.
If she didnt feel anything for him you would know she talks to him and you would talk to him as well... if she secretly does it she obviously still has feelings for him. Or it bothers her that you still talk to your ex...

If you still have feelings for your ex then let him/her know that, then you both decide if you still have a chance togther.
Dreams often reflect our subconscious thoughts and feelings. Your dreams about your boyfriend's ex girlfriend could be a manifestation of your insecurities or concerns about your relationship. It might be helpful to openly communicate with your boyfriend about these feelings to gain clarity and reassurance.
well look for signs does he still talk hope it works out
If he has moved on and has a new girlfriend it is time for you to realize it is over and move on as well.
don't do it.
