Families 😣

How do you guys deals with your unborns child family not liking you ? Me and my boyfriend has been together for 4 years in dec. we will make 5 and now we’re expecting his family has never liked me but before it was never something I knew about they don’t know I’m expecting yet but we recently got back together and I know for a fact they don’t like me , he cheated on me about a year ago and I knew nothing about it but my women intuition said something is wrong so I left him completely to find out he had been being another girl around so his family loves her and isn’t going to stop having her around although the has told her and his family he loves me and how he is working things out with me (last year October) as well as (this year) .... it’s really hard for me cause who wants to keep their boyfriend away from his family but who wants to go around a family who not only dislikes u but keep around a walking bad memory of ur past ? ....he is so happy we’re starting a family and I am too I just can’t accept the bad relationship between me and his entire family nor them keeping around a girl who has no purpose but it’s out of me and his control .
