Hi na- I can relate completely to your trust issues. I had them coming into my M (my first H cheated and lied continually). After time, I finally begain to trust my H but then WHAMO!!! I don't know how I will be if my H ever moves back in with me. I feel pretty comfortable right now because his actions are showing me that he wants to be with me but I know those ugly thoughts will start popping up if there isn't a lot of consistancy. I know it will be something I need to work on with the C if my H and I make it that far. For you, I think the C next week should really be able to help you and your H deal with your trust issues...especially since your H seems to be willing to do the work...another positive.
Glad you had a nice family trip...and yes, I remember vacationing with little ones and they weren't very relaxing...oh well, maybe it is time to plan another little getaway with just your H if possible.
