Wtf rant

Okay so I’ve about had it, I’m currently in a living situation where I stay on one side of a house. We’re trying to get our own place but it’s been rough. It’s my 3 kids and my fiancé and I, my fiancé is currently working out of state so it’s just the kids and I. Well anyway, my future brother in law is living with his pregnant girlfriend on the other side of the house. So the problem is that he wants the thermostat to be turned down to 65 degrees. 65! That is beyond freezing for me, the kids end up with runny noses and my oldest has asthma and it acts up. The thermostat was at 72 and it wasn’t ever a problem but apparently since he moved in his girlfriend it is now a problem. I agreed to move it down to 70 but anything lower I can’t do because like I stated before, my kids end up with health issues. So my future brother in law decides that he can’t agree to that and he wants it at 65. I told him no and if he can’t agree I will bring in momma dukes. She owns the house we are staying at, well I had to bring her into it. She agreed with me and said that it can’t go any lower than 70. Well I guess he had a bitch fit about it and continued to complain. He’s trying to state that he doesn’t have kids and he pays half the rent. Like wtf we pay half the rent too, and what the heck does me having kids have anything to do with you moving it lower? Sorry about the long rant I’m just fed up.
