Relationships can develop in time. I've had to really work on my T not to leave those huge long silences waiting for me to speak. I'm pretty adept at silence and it irritates me when he tries that technique because it's one I use in court and depositions a lot.

You may just need some time to adjust to each other. Definitely tell him about the interrupting thing - no one needs to finish your sentences. Oh, and my husband gets a weird cough in the winter. Maybe it's just a temporary thing.
