I’m so lost

Ka

Hi I’m sad I got engaged on the 29th of December and on January 20th I went to go pick my fiancé up and I told him that me and my sons father been arguing cuz he thinks I’m trying to keep him away from him which I then told him he can keep our son for 3 days then my fiancé gets attitude basically telling me to drop him off and don’t ever say nothing to him broke my heart I thought I was being a women and telling him what’s going on.... I’ve been pregnant by my fiancé 4xs and was just pregnant with twins but loss them... my stress level is high and when I stress it goes beyond my heart is hurting I’ve been with him for 3 yrs and I’ve never cheated or gave him a reason to think I cheated on him... he blocked me off calling him and everything this pain hurts cuz everyone I talk to tells me I did nothing wrong.
