I don't know what is going on with SO, but seriously getting tired of how he is acting towards me. I literally was in the middle of talking to him about the baby and he got up and walked into the garage to smoke a cigarette and play on his phone... And I told him he wonders why I 'appear sad all the time' and he said no I'm aware. DUUUUUDEEEEE. 😕
