I do that same thing and my pregnancy has been so emotional and I have been depressed but I don't want to take a higher dose of my medication bc even though it's safe for pregnancy I am just worried it will effect my baby. With my boyfriends Facebook it's not rly his exs though that drive me crazy but how he used to post about how amazing we were together and how much he loves me and it's been two years almost and he doesn't post anything on his Facebook anymore.. It's depressing! I know how you feel though and that would drive me crazy if I saw things about my mans exs on his Facebook... It would piss me off. Talk to him about it, maybe he doesn't even realize that stuff is on there. Idk Hun good luck !
