Help me ladies😒🙄

Well I'm currently pregnant with my boyfriends baby, I'm almost 5 months. And I guess last night while I was sleeping my ex BF texted me a long paragraph thing saying he loved and missed me and it was out of no where. But I pressed charges against him for domestic abuse last year so why does he still love and miss me? Idk or care, but I'm pregnant and my new life is starting I don't need this shit from my past popping up, So I didn't see it till I woke up, guess my boyfriend seen it when it popped up lastnight but now he's mad at me for it.... I didn't reply and now everything's my fault and he probably assumes I'm cheating, great so what do I do now, I know my boyfriend is hurt and stuff I would be too but I shouldn't be the one getting blamed for this mess I didn't do anything wrong.. Now he's barely speaking to me and mad.
