Im really scared !! 8 months pregnant and boyfriend cheated !!! 😭

I’ve posted about how I forgave my boyfriend about 8 months ago for entertaining other females! I gave him a chance because I thought maybe he can change and he only did it on a drunk night not an excuse but I let it slide for the sake of my family. I worked on my mental health and trusted him more and I occasionally peeped at his phone but never gave me a reason again !! Except tonight in the afternoon I open his phone because he left the car to pick up my Stepdaughter from school because it charging and this number called so I answered and it the school because we forgot to tell her a pick up point and he couldn’t find her ! I then ended up staying on the phone because my phone died n I didn’t wanna take the charger because he just plugged it in and I was bored and one of the applications one was fb message and a saw a message that said hey babe soo obviously I was like tf is this right but I clicked it n that was the only message so I ignored it and moved on through the day without saying anything I went to sleep and I woke up at night n I was so paranoid I went back to see if he had responded but the message was deleted n the only message was there was a response from her that said ok handsome and then a PICTURE OF HER NIPPLE SO OBVIOUSLY HE RESPONDED N DELETED THE MESSAGE N NOW IM DONE!!!!! I’m 8 months pregnant and scared because I don’t wanna be at his house anymore and I have no where to go ! He’s sleeping right now and I don’t even wanna talk about it because obviously he’ll never change ! But I’m not stressing it because all I have to think about is my baby
