Pregnancy hormones or overreacting ??

So sorry in advance this might be a long post...

As of now i am 28 weeks pregnant this pregnancy has had my hormones all out of wack as i cry for everything. A few days ago i was going through my husbands phone and saw a bunch of txt messages between him and his female co-worker were they have this what seems to me a really good work relationship. She is always nagging him how hungry she is and askinf what they are goinf to eat for lunch he is always offering to pick up lunch for them both and vice versa. The other day he texted her a pic of some biofreeze because he had hurt his ankle at work and she responded with a “aawww poor guy must suck to be old”.

I took it at he was seeking her attention (i might be wrong but that is how i feel) in other words my point is there always constantly texting all day long.

The part that hurts me the most is that now that im a stay at home mome i Am literally all day home alone with no one to talk to but my 16 month old. He complains all the time how much he hates work and cant stand beinf there but reading their text messages it doesnt seem

Like he has such bad days bcuz they are always talkinf and joking. He seems to always be in a bad mood with me and always seems to make me cry with his comments and doesnt even apoligize or feel bad about making me cry. The other day i cried bcuz he started complaining that i feed my child cat food (it was tuna fish) with vegetables and that y cant i feed her normal people food. I almost feel like i should be the last person he should be mean to when he comes home crabby from work.

Idk ladies i could be over reacting or overly emotional bcuz of my pregnancy but should i be concerned about his relationship with this co worker ??!!
