Tad, brother ... I don't care how old the gf is ... if you can't pick your S17 up at the ex's place without it sending you into a funk ... YOU AREN'T READY TO DATE.
And your gf doesn't know this 'cause she doesn't have the experience or emotional maturity to know what a strong, emotionally healthy partner looks like. Hun, it ain't you. Not yet. Not now.
TAD ... buddy, why do you even care "how" involved the ex with OM? You've moved on ... you're with someone else? I suspect, mostly as an ego boost and an attempt to make the ex jealous.
You've got it in you to do what it takes to move yourself forward. But you're too afraid to do it. You said it yourself ... you're even to scared to go back and read it all again. DO IT. Over and over and over again ... I had to, and finally some of it seeped in ... then it started to make real sense. Not "oh yeah, I get it but I'm not doing it sense" ... actual honest to goodness lightbulb, AHA! type moments.
Peace PEI
