Has he lied to you before or is it all coming from your depression? Maybe he has a deadline so he works a little later. Maybe he just needs a little breather while you are "in the darkness". He can't fix it for you and that fact makes the ones who love us feel helpless. I tend to await rejection because I know how difficult it is to take my illness: I don't want to be around me during the down times, why should he? But all that comes from inside me, not from anything he does. I know you can't control your thoughts but at least try to control expressing them to your boyfriend until this passes. No one likes to be accused of something they are not doing. Just hang on. You will come out of it. We always eventually do. Hope things are better soon.
