Am I being stupid?

So my spouse and I, we have great times but we BARELY can hold a conversation longer than 5 mins, before and after the baby. I like her to go out to hang with friends, but she just loves being around them can talk to them for hours on end, like 8+ hours just having so much fun. I'm just home upset , crying in bed, because I wish we could Be like how she is with her friends.. so naturally I'm upset.. I don't know what to do. We love each other.. but i feel like we don't click.. or something. Any advice? We try to communicate. I feel like we're at a dead end and it's not even a bad relationship. We just don't even talk really. She's military works long hours. I'm away from family naturally and I'm fine with being and supporting her. But not talking to her my only family here besides my baby.
