person A: I hope this doesn't make me sound like a horrible boyfriend_comma_ but when my girlfriend first moved into my house_comma_ I felt very apprehensive towards the move at first. I was used to it being one way_comma_ and she was changing everything. Took some getting used to.
person B: I'm sure it did! It's not easy to have to adapt to another person's habits.
person A: I know. It caused some tension the first week or so. I had to take a deep breath_comma_ and realize its just things_comma_ and it was just me being reluctant to change. 
person B: Yes_comma_ sometimes we have to learn to let go of the little things so we can appreciate the more important things. It sounds like you have done a great job!
