Greg, thank you for your reply--you had a great deal of insight
As far as trust you hit the nail on the head but it's more of a different level of trust that's the problem. I trust him more to not have another affair; I trust him less when it comes to other things. Bottom line though it's still an issue of trust. I think things went bad at New Year's. We went out with a group of friends, he had too much to drink and then thought it would be funny to lift my dress up in front of eveyone while on the dance floor. Since then I've kind of gone dead inside. We've talked about this a few times and I think he's finally understanding my deep level of hurt.
And then there are the little things that chip away at the trust. I don't trust his driving--too fast, doesn't pay attention, etc. then he forgot to pay our health insurance, then there was the time he left our children home alone for a half hour (ages 3 and 7). It goes on. We've talked about these things and I've been firm in setting boundaries and what I need yet here we are. You're right I need to keep communicating and I think that will be my next step with him. thanks, greg!
