my husband decided to leave me

hi ladies today im 5 and 3 days pregnant it was very difficult to get pregnant with my second baby (this one) i had two mcs last year ... a week ago i found out that im expecting im so happy ❤️ but at the same time im heartbroken 3 weeks ago i found out that my husband sent some pictures to a "lady who only give him the route of jobs that has to be done " the excuse was that he was drunk that day and it was a mistake but he lied to me he told me that she was a old lady ( but she wasnt) i found out that she has the same age as us and i dont understand why he lied ... i confronted them and both denied everything but 4 days ago she call him around 11 pm i picked the call and she was like "Hey" i got mad and asked her why are you calling my husband at this time? she was like its just for work " " he was texting me and i decide to call him" but he was drunk that day too i told her "my husband doesnt work 24-7 "so it was weird for me... so i decided to send a msg to her husband telling him everything and he say that he will talk to her bc its not right .. so my husband called me super mad asking me why i did that .. that she got in trouble with her ex husband and that she was separate from him but it was a lie they are living together so my husband decide to leave me just because of this situation but i know he is doing something wrong he hide his phone , turn off the volume and now he is sleeping in the other room using the phone all night .. he wasnt even happy about the baby he had no reaction and it was very painful for me idk what to think or do . he has to much pride 🤷🏻‍♀️
