I am pregnant with my 3rd baby, my fiance has let me down alot over the 7 years i have been with him. He has stole from me ran up debt not contributed to household bills. I pay my mortgage own my car an provide for my children and i work full time. He smokes alot of marijana which i let him do as he is so hard t live with without it. Anyway i have just found out he is texting other girls. Am i being hasty telling him to leave?
