I feel stuck

I feel like my fiancé has no good communication with me what so ever. I feel that his guy cousins and brother are more important than his family myself, our son & unborn daughter..he basically ditched us this morning and is with the guys instead. This week we are suppose to put down the deposit for our new home..I just want to cry cause I deal with this all the time. We been together for 8 years and I just want to be happy I know everyone has there ups& downs but this had happen before 😔
