Rant time...

so my sister is due Friday with her first baby. she moved in with her boss about a month ago, to help him with bills because his girlfriend of 5 years and mother of his 2 year old had just passed away in a car accident... I messaged her on Facebook to see if we can hangout tomorrow because she has an OB appt right by my house, and she said "I will have my other son with me" and I was confused for a second then she said that her and her boss were together, and that his baby was calling her momma now, and all this sh*t. and I'm sitting here like how the hell is he gonna just move on that fast from a 5year relationship and the relationship ended without them wanting it too?!?!? then she says "if your not gonna be supportive then I'll go talk to someone else" and I'm like wait a second.. why should I be supportive of you dating your boss, and knowing that his gf just past away, that is just f*cking wrong. I could never even imagine moving on from my husband that fast and we have only been together since November of 2014. I really don't understand what my sister is doing with her life right now.. and to top it off she is living in the house that him and his gf shared for 3 years, with all of their pictures on the walls and everything of hers still in his closet.. like really?!?! I'm just so confused...

Okay rant over! (please no rude comments towards my sister)
