Summer fun??

Soon we embark on our summer adventure.  It will be my boys' first time on an airplane.  We are going to visit the 'other half' of my boys' family.  My former in-laws are having a family reunion, and we're invited.  They want to spend time with their grandsons, and I'm the gatekeeper, so to speak.  The ex will be there too.  It's going to be the first time we'll be together for an extended period of time since the separation, which was over 2 years ago (but seems like a lifetime ago).  I am having lots of mixed emotions about this.  I am not a natural traveller, to say the least, and this is certainly not going to be a straight-forward joy-filled occasion for me.  It may make me feel like a pile of crap, and reload guilt on my plate that I've already tried to wash away.  I don't want my boys to get 'confused' about the status of their family.  I think this is highly unusual, for a woman to spend a week with her ex's family.  I'm doing it for the sake of the kids... and hopefully, I come out of this a stronger woman, more sure of myself and my decision to leave the marriage.  I know I deserve better.  I know he treated me like crap.  I know I don't want that ever again.... and so, I can do this.  I can do it.  God help me!
