I did that maybe like a week after i broke up with my last serious ex...we were still speaking though, but I was getting too enraged when I'd see a guy leave a message on her wall or "like" a pic on her page...that was no bueno for me, so I just hid her feeds from my page and haven't looked at it since that day.....and it's been almost 6 months since. Being that we broke up because of going back to long distance and it made sense to break up, I didn't even have a legitamate reason to be angry about anything. But I can't lie, regardless of who i'm with now, I still sit back and "Stevie Wonder about her".
...and i know for a fact she still checks my page, she'll send a random email asking how i'm doing and will bring up if she see's I added a new female friend on FB....I don't even reply to her emails like that anymore. I've just accepted we both have met other people, but I don't wanna see it on her part.
