Can marijuana effect relationships?

my bf smokes it, and evrything, and i dont typically like smoking or smokers but i tried it with him just to experience it with my bf, cus i love him and ive only done it 2x becus my grades werent too good so i stopped and ima A student and i didnt wanna ruin my future. but i love him for him and his personality, but i sometimes hate it wen he smokes n gets high, it feels like he's more careless and and isnt all that attentive n i feel so irritated at him. it feels like wen hes not high and watever that hes just soo much more attentive and idk just different, but i wanted him to stop smoking becus he got bronchitis and i wanted him to get better, but he saids hes done with it but on facebook i see him commenting his friends status talking about how high he is or something and i get a lil upset cus i feel like he wont even stop for me, and he tells me how much he loves me high or not, but just wen he's high i just dont feel rite talkin with him, cus he acts soo annoying with his random giggles and he doesnt take things serious, n it gets me irritated, i made a sacrifice for him i wish he'd do the same for me, and idk i just feel more connected with him wen hes not high, like the person i fell in love with becus wen we first dated he was on probate n wen he knew he was off he smoked daily!
