Good job nuking the FB ... I know I would get pretty irked when OM 'liked' something she posted .... for about a year thats all her ever did, then one day he got brave enough to actually comment on her trip and I about lost it. I recall looking back thinking .. "Now everyone knows they are Fu$%ing" ... his comment 'safe travels' .... its actually funny now what a lunatic I was at that time to me.
I rarely to this day go on FB, W says she has'nt in a bit ... I have not looked nor really care to, she still has me blocked ..... though I can access hers at anytime (quite boring now honestly)
The one thing/piece of advice I will give you .... no more "I love you's" .... she knows ... trust me, and you saying it just lets her know what she has done and is doing has little consequences. I recall my lesson what that one ... I said ILY and her reply "I know" stung so bad I vowed that day never to say it first ever again.
Hang in there ... it does get better regardless of what she does.
