Alright well it's time for my first rant about my boyfriend. 95% of the time he's great but today ugh I just can't. He started smoking cigarettes again even though he told me he stopped and I've caught him a couple other times and I sent him a message about how I don't want him to because of cancer and our child thinking if dad does it then it must be ok and then today he just grabs a lighter like no biggie as he's walking out the door and I asked him what he just took and he said a lighter then tries to kiss me, I'm sorry a lighter for the cigarettes that you told me you stopped smoking?!?! I have back pain every night, I'm more and more uncomfortable every day, I can't drink, I don't party I'm not supposed to stress and he just takes up smoking again like its no big deal! I tried the nice way of going about it, the lets talk about it together and figure out a solution and his solution is "he'll quit once the baby gets here" no that's not a solution because that may or may not happen! Ugh I'm so frustrated right now and just sent him an "I'm done trying to be nice about this, I'm actually furious" text.
