My boyfriend and I got into an argument a little bit ago. I said some stupid things and then he said some hurtful things so we're both sort of at fault. Anyway after he said what he said I handed him the baby and said I was getting in the shower (that is the only alone time that I get and I cherish every relaxing moment- everyone needs that). I'm sitting down in the tub letting the hot water fall on me and my boyfriend comes in like "the baby is crying, he needs you." Seriously? I can't even get 20 minutes to myself? Just because he is crying doesn't always mean that he wants to eat. He could be not feeling well, he could just want to be cuddled. He could handle some of those things with the baby it doesn't always have to be me. Ugh, anyway rant over. Sorry I just feel like I don't have anyone else to talk to about it.
