Pre/post partum questions-I don’t know how to feel

Amber

I feel horrible for having these feelings but I don’t know how to address them or talk about them with my SO. I am a step-mom to his 5 year old son and have been really resenting him the past week he has been with us. I work from home so my SO leaves him with me all day long. By the time he gets home from work, his son is already in bed and falls asleep within 30 minutes of him being home. He doesn’t realize what I go through all day having to take care of his son all while still trying to do my own work because I am still working even though it is from home. I am due October 9th and this week has just made me fearful that I am going to miss out on my “first-child/first-time mom experience” because his son requires so much attention that I would much rather give to my own son. I just feel like I am missing out on something that my SO got to experience and I don’t get that now. I know that sounds horrible and I hate having these feelings. I don’t know what to do.
