Am I over reacting?

So my husband got a new job as a security his ex military and some of the workers he works with are also ex military. There’s this particular girl on his job who he talks about a lot.. I mean on how they mess with eachother what they call it “talking shit” and apparently she shocked him out today in a playful way. Mind you this girl is also marry and her husband is currently deployed in Afghanistan... now yesterday he asked me to make his fav food for lunch to have some of his coworkers try it and I said yeah sure... we’ll I couldn’t help it but I went on his phone and notice that he txted her saying “hey I got lunch for tomorrow” and she replied with “awesome your the best battle” so I didn’t think of it to much... idk if I’m thinking to much into it but I know for a fact that if I was that close or talked about a guy as much as he talks about her it wouldn’t fly with him and it would of been an argument.. am I crazy? I’m a stay home mom and I also attend school so going to school is the only time I get free and get to talk to others.. I’m thankful that he works and also attends schools but I feel like I’m left out.. he comes home eats, showers, and goes straight to his phone or video games..and when we do talk it’s about this girl..I get that his job may be exciting and that his exhausted from it but I just feel left out and it’s tiring also being at home with a one year old and not have quality time with my husband.. 😔
