What do you think ??

So I have a question for you guys . How long do you introduce your boyfriend/girlfriend to your parents?? I’ve been with my boyfriend for a year now and I’ve been at his house and I still haven’t met his mom .. he’s always saying she’s tired, her schedule changes, met us at Disney but later his “mom” would say she looks terrible and tired. My boyfriend already seen my whole family by 5 months together... the days I would go to his house was days I had off and he would tell me “your finally gonna meet my mom “ but once im at his house he would be “she actually works today “ .. It’s actually been bothering me , I’ve told him once and he didn’t say much and now it’s bugging me again .. I need advice girls 😕

today I asked my boyfriend if he’s coming Christmas eve or day ?? I told him I wanted him Christmas eve if it’s possible.. he told him mom and she got upset and of course I got upset and emotional... I’m most likely not seeing him on Xmas eve/day because his mom wants him both day.. he told me the family is getting together on Christmas eve! So why am I not seeing him on Christmas Day ?! just GREAT !!! Now wtf am I suppose to do ?! Am I overreacting??
