Rough patch

I feel like things the last month has been going down for me and my boyfriend... I feel like he's just sick of me . He literally seems to get so frustrated at everything i do or say and it's pretty upsetting .. he seems to get mad over little things lately and I'm not sure why... tomorrow is my bday and I just want to enjoy my day I wanted steak fajitas for dinner and then I told him it looks good and then he was just complaining saying it's going to be too chewy , he's making them anyways but one min he's fine and then next it's like he's moody .. he used to be on an anti depressant but hasn't been on meds for a year.. but he seemed more relaxed and what not when he was on them . Normally we smoke grass and he's very relaxed and funny but he just seems so tense idk what to do
