2 weeks really will just fly by. You'll be doing something that you like doing and socializing with your family. Try to set something up with Karma so that the two of you are talking/texting/emailing daily just to touch base with each other.
My hubby and I still have our connection and he was gone for the better part of last year. It will be ok. The 2 weeks apart will likely just fly by. Plus getting back together after being apart for a while is always fun.
If there are things that really bother you about Karma and Cricket being together while you're away make sure you voice exactly what those are. For me while my hubby was away and had just met his gf I wasn't ok with overnights because I didn't have the oppertunity to have someone sleep beside me and cuddle with at night. It was a very specific request and he respected my boundaries.
Hope that helps
Everything will be ok in the end. If it's not ok it's not the end.
