I seriously wish my SO would understand that it upsets me that his sister had the nerve to say something so negative about me smoking marijuana and not being able to come to me. I get it not everyone has the same observations but it's something I've consulted to my Dr for my depression or for my migraines as of now yes ive backed away from it because im pregnant but it just upsets me she couldn't be women enough to come talk to me but speak so negative in front of his WHOLE family. like ive talked to his mom and shes understanding and of course she has her negatives but she was open to it & understood that all the meds I took were ultimately just worse... like it's changed my whole views on her and ever since I've disliked her ya i keep it civil but it's causing problems within my relationship now and it's seriously annoying that she tries to kiss ass or tries to be fake like I'm not ok with that. I want to be cool with her but just to know she can't come to me makes me real upset and makes me second guess that she even likes me. I hate it. I don't want to dislike her but it's been so hard when. she's just a phony.
