I agree, recognizing the problem is the first step, and now you may want to find out what is causing that extra stress you've been having lately.
(whatever it is I hope and pray you can fix it )

Maybe Remus is sensing and "channeling" your stress and that's why he's been more nawtee than usual OR maybe that's the way he's using to complain about the way things have been between you two...
Whatever the case I hope you can work things out, love makes it easy!
