Craziest day of my life! 😖

Just to start off. This is a vent. Don't have a lot of friends who wouldn't freak and ask me if i was insane. I'm currently 14 weeks pregnant. Very high risk pregnancy. My boyfriend and me have been together for close to 2 and half years. When i met him. He was with someone else. Please no judgement. It wasn't like how most people think of it. We were never intimate with one another. We were friends. I was aware he had feelings for me and he was aware that it was mutual. We both were going through some stuff with are partners but never crossed the line. Judge if ud like but i think all feelings aside we handled are situation well. Anyways today my boyfriends wakes me up about 4:30 pm. I work nights and hadn't even gone to bed tell noon. Anways. He tells me that his ex and mother to his youngest was kicked out of her place to live. That she was dropping off there daughter and going to a homeless shelter with her other 2 kids. My head started pounding. Biggest head ache of my life i swear. I looked at him and said. Tell her she can come stay here with her kids. Are furnished basement which use to be a play room was not being used. My BFs brother was and has been for almost a year living with us in are spare room. She took the offer and moved in today. I ran 30 mins away to get her an queen air mattress and a twin bed for her kids from my sisters. Even gave my bf 120$ bucks to give her so she could buy groceries for her kids. Sense are house is empty pretty much. Do to the fact me and my bf work a lot.She doesn't like me. Given shes thinks my bf was cheating on her with me. Maybe emtionally but not physically. Even once accused me of abusing there daughter. Even though ive never been left a lone with her. My bf is an awesome dad and spends time with his kids without my interference. I could go into some more of my own insecurities on the matter. However i am happy that her and her kids are in a safe environment. I just hope this doesn't back fire in my face. Wish i wasn't so anxious about living under the same roof. I can tell even my bf is worried about me. I do feel like being upset but im just not that kind of person to leave someone in need like that.

Currently sitting at work. Exhausted after 4 hrs of sleep. Not off for another 7 hrs. Trying to just keep myself calm.
