Husband

Hi my husband and I just moved to a different state together and is in the airforce we are young too and he says everything is fine could be in my head though he hasn’t said I love you to me I always say it to him most of the time and he is not a emotional person but that worries me sometimes he don’t get mad or upset or cry or anything and he hasn’t been talking just kinda complains about everything trying my best to help him and make him happy but not sure if everything is alright though but we are still having sex and he knows I haven’t been taking BC and now I could be pregnant and he don’t seem he is very supportive about it and iv been having self esteem problems what does everyone think ? Could use advice
