Just found out my bf is cheating

Like wtfffff I’m just here to vent but I couldn’t even breatheeeee like bro I’m 20 weeks pregnant and he’s calling this girl babe and trying to be more than friends I’m so sick of men atp I’m tired of everyone! And we had an amazing day yesterday I was so happy he really made me happy and were actually getting dressed now to go on a fucking date but he’s sleeping. And then I saw he text another girl but she was curving Jim she don’t want to have sex with him anymore cause he always disappear after like omg I can’t take this and I don’t know what to do at this point. He even sent hearts to this girl story the other day like wtf she’s literally married and I just reacted to her post too 😭 I also have her as a friend. If I see this on his work phone I can imagine his personal phone smfhhhh. Like whyyyyyyy is this happening right now whyyyyyyyyyy

Edit: I confronted him about it and he denied everything but I already seen his fucking phone and he’s so calm and collective like I didn’t say anything to him….. he said he’s not talking to anyone and he’s not being fake bla bla how can he sit there so calm and just lie like that
