Stressed ? Opinions?

So my SO has been “stressed” but the person he takes it out on is me he laughs with everyone else but me or my daughter he says it’s money that he’s tired living check by check but he doesn’t say that when he buys expensive shoes etc I’m dealing with it cuz of my daughter I want her to have her family but it’s to the point where he barely wants to talk to he’s very distance and dry in the conversation but I’m still manage to try and try so hard but I’m so tired of it I’m so tired of being the only one trying here I don’t even know .. opinions plz should I just be understanding towards him am I being dramatic ?
