Feeling alone in parenting

So my husband is active duties in the marines. He recently got deployed again and have a 4 week old. I'm lucky he was even able to be at the birth. And look. I get it. I'm not allowed to complain. I married someone in the military. I had a baby with someone in the military. I signed up for this. I just hate that I feel like a single mom. He sent me pictures of him at base and his other soldier friends got in the picture. It just hurts that he gets to be around people and friends and I can't even get a shower in. I can't do anything. I have sent him pictures of the baby and he loves getting them and I do like getting pictures of him. But when the picture is him laying on his bed or other marines are in the picture it just makes me so upset because I can't just lay down and I'm so tired. I actually fought with him a couple hours ago. He was trying to talk to me over the phone but everyone was being loud and I was just so upset and said "Good you get to have fun while I'm here with a baby! Someone has freedom!" He said "I signed away my freedom when I joined the marines soooo." And then we just started fighting over the phone. I'm not trying to disrespect the military and I'm sorry if anyone in the military feels disrespected. I know its hard. Especially the marines. I was just so fed up and tired. I shouldn't have taken it out on him. I wish I was able to be around people like he is. I wish I was able just lay down. I wish I didn't feel so alone...
