I get tingly when I see any communication from him too...I think when we are truly detached we are just calm and not stressed about the outcome.  When we are in expectation/control energy we are wound up in knots.  I think we just have to repeat often "X loves me.  I know he loves and cares about me." "Everything is happening in divine timing."   Eventually, it will sink in.  And when we veer off track (it happens--majorly to me this week!) I just took a break from anything to do with him, focused on self love again and today I feel totally re-set and back on track.
