I'm no fun anymore???

S

So I just had my second child three weeks ago, I'm still on maternity leave and basically caring for my newborn and 2 year old for 18-20 hours out of the day by myself. My newborn does not sleep well at night so if I'm lucky I'll get 3 hours of sleep pieced together throughout the night. My fiancé works overnights so when he gets home at 7am he goes straight to sleep and sleeps until 3pm or so. After that he kinda just does his thing, video games, fishing, etc. while me on the other hand am cooking, cleaning, bathing the kids. Of course I'm a little grumpy with him when he gets 8+ hours of solid sleep a day and still gets to participate in his hobbies. I'm exhausted. Being at home with 2 kids is so hard! So yesterday I brought it up to him that I expect more help. That yes, I know he works all night but he only works 8 hours and then he gets to leave. Me, I'm doing this job for 24/7, I don't get any breaks. (Honestly have a newfound respect for SAHM's) That leads to a small argument where he tells me I'm not fun anymore after we've had kids. It really hurt my feelings, maybe it's just hormones or lack of sleep I don't know. Relationships change so much after you have kids but I feel like the mother's life changes more than the father's. I don't know the purpose of the post, maybe just the went and get this off my chest.
