Good relationship wit exs family

anno

So my ex and I broke up about a month ago bc he cheated , I found out I was pregnant and now he's with Tighe other girl . But he's whole family loves me and is not welcoming the other girl . They invited me to Christmas and I'm still really close with his mom . I'm going to go to the Christmas but idk what to do if he shows up I do t think he will bc he's not really talking to his parents rn but bc of other reasons . But I still want to be prepared like do get up and leave or stay there I mean I'm not going to feel uncomfortable but idk is it weird if I stay. And if brings that girl with him my feelings might be hurt a little bc I do still love him , but I also want to go bc I want her to win ya know
