Downfall :'(

I think this is it. I think my husband is done.ita killing me inside. We have 1 beautiful little girl that just turned 3 in April we have been trying for almost 2 years for another baby with multiple miscarriages. I feel like he resents me. Every time I buy a pregnancy test he gets all cold towards me telling me not to get my hopes up. Today we are fighting and haven't talked or looked at each other in several hours. My daughter is leaving to go to my mom's for a week before it's time for school. I'm wondering if I should go with her and just give him space. My heart is breaking. What do you think i should do? Am I being stupid?
