Feeling disconnected ☹️

Been feeling really disconnected with my husband the past few months. Ttc has put so much stress on our relationship. We just started the ivf journey and I feel he’s been MIA. He works a ton but when he comes home he’s been passing out or watches sports. I usually put our 4 year old to bed and go to bed. I haven’t even seen my husband all week. I told him we needed to discuss some things this week that it feels like we are roommates and not even married lately. Ugh any advice?
