Vent..Frustrated

My son has had a mild fever since Thursday. It was 100. Here we are on Saturday his fever went up to 103.7. I called the nurses line and she said to have him seen within 24hrs.. now I tell my bf which is his dad and doesn’t want him to go saying stuff like fevers last up to a week and you’re a over dramatic bitch. Just straight cursing me out because I want my son to be checked out. He’s constantly belittling me and any thing I say. He has to control everything. Like what is this? Is this a form of abuse? I feel so little right now and I hate it.
