All you can really do is let him know that you are willing to be there for him should he decide to come back to you. But chances are, if he still loves you and wants you back, he'll find a way to get back to you.

My boyfriend in handsome and he thinks I'm beautiful
He's your boyfriend -- it doesn't matter what "everyone" else thinks. But if you have suspicions, the two of you should have a good talk. You owe each other that much.
well, i think you should just ignore it and if he does it a lot, THINK about breaking up with him.
Then that should be enough. If he still has a problem even after you told him that then don't bother. You can go on without his approval anyway, especially if he's your ex.
Just do it to him again and again
first of all, why does he think you are annoying? i would find out what it is and then try to work on improving it.
You look for a new boyfriend.
That depends on what your boyfriend thinks of that. Does he know and is ok with it? If he knew, would he be ok with it or would he feel hurt? If you're aware that what you're doing hurts your boyfriend or would hurt him if he knew, then you should stop if you care about him. However if he knows and doesn't mind or if you are sure you could tell him and he wouldn't mind, then it's no problem.
if she is happy with her boyfriend then leave her be but if you think that it will benifit her lifestyle or her happieness then tell her
