Well, maybe it's some of all of the above. A little of this and that. Right now, wouldn't you rather just heal from this, then go onto something else? I am a firm believer in clsing one door before opening another. You cannot drag in yesterdays news, if that door is shut, right? Right now being unapproachable might be a good thing. You are hurting, and when we hurt we tend to be vulenerable...no need having hawks come in and prey on us.
Unrealistic expectations? Are you looking for Mr. Perfect? He has no flaws? He doesn't exist. If you go by your core values, morals, and characteristics you won't go wrong. You may not find as many fresh perch, but you will avoid sharkm adn baracuda!!!
(((seame))) you will get past this, just give yourself the time you need, and know who you can count on.
