Understanding the modern day ego

I'm noticing a lot of (potentially unintentional) shade from specific people in my life... And perhaps this of no fault other than my own. 

I'm not the type of person to reach out.

I make the common-day social gesture and text; comment via social media--I don't call.. Partially because the distance I've already placed makes it difficult to maintain current contact information (phone numbers) for everyone I communicate with-- I still reach out when I can.

Most of time, I don't care if they don't respond. Shit, I have a life full of daily demands... A child to care for, groups I belong, committees I respond to, and people I click with, not to mention the chores and responsibilities of being a full time mom/ working bread winner/ and chef. 

I make due with the time I have. 

But whatever.

I usually ignore the discontent I have and eventually the 2nd or 3rd attempt I make reaches through and they respond. But in this situation, I feel completely ignored.

I can't help but feel this channel has been closed. Perhaps by conditions beyond my knowledge have put a cease in these people's contact with me because it has been seen as something accessory to their own life.

In which case, I am saddened. 

Have I become someone so remote; so distant that I serve no relevance -- no viable mean of communicative support? 

This is so disheartening to me and so self-damaging to contemplate.

I'm working towards a better understanding of them in a reflection of my own ego. 

I'm trying to learn how to not take offense, but this alienation has made me feel... Well, alone. 

Sooner or later, this will subside and I'm certain this will no longer burden me the way it does now. 

I won't hurt... the way these people are possibly trying to hurt me. Maybe even subconciously.

And that--- is the underlying MO of suffering.
