Is it right to expect your boyfriend to be honest with you about certain things?

It isn't unreasonable to expect honesty in your relationship. What he needs is a dose of 'if the shoe were on the other foot'...

Remember what he said? 'His business is his business'? Well, just randomly text someone (a friend) or check your email on your phone about every hour...in front of him...but where he can't see what you are exactly doing. Walk toward another room...go to the bathroom and lock the door... Don't tell him what you're doing if he asks...just say 'nothing' and practically ignore him. Now, be sure whatever you do is really on the up & up though. If he secretly checks your phone don't be texting/msg guys, or talking about him to other ppl. It would really piss him off and backfire on you. Keep your phone where he can't get to it without you catching him snooping. When he gets all curious, bent out of shape, or insisting on knowing what you are up to...that's the prime opportunity to say: 'as you stated before- YOUR business is YOUR business...and I am telling you that MY business is MY business..or do we have a misunderstanding? If you are free to talk to anyone you wish, the same goes for me too...or do you have a problem with such an arrangement'?
Just understand that you will have to learn to quit worrying about it before he will be comfortable opening up to you.

Honestly, unless he's got children with the ex, what's the whole attachment & conversation thing about with them anyway? She's not his gf anymore, and not likely his best friend. Maybe he likes playing jealousy games, or is still hung up on her...Either way, you gotta fight fire with fire to get anywhere with this guy. If he acts totally uninterested in what you're doing, it's a sign he really doesn't care about you or what's going on with you because he's distracted and occupied with someone/something else. Can't get any more straightforward than that.
