My Boyfriend (M24) doesn't understand why I'm (F19) afraid of fleas

On Tuesday, I (F19) went to visit my bf (M24). In LA there's a curfew for when we can go out (it was 6am-6pm) so i asked my mom if i can sleep over and she let me cause i wanted to spend more time with him. When I visited him, we had a lot of fun together in the morning and in the afternoon but then we fell asleep on the bed after having sex. When I woke up, there were like 5 black dots on my socks. They were fleas. I was really disgusted and asked him to kill them for me. I did notice I was itchy in the morning but I didn't know why till now. It was like 9pm so I couldn't go back home so I had to sleep over in my boyfriend's flea infested home. I didn't want to move because the fleas kept latching on to me when I walked around the carpet so I literally sat on the chair for like 6 hours till it was like 3 am and I was really tired. He wasn't bothered by the fleas and didn't even notice that he had a flea infestation till I came over. When it was on his leg, he literally did not give a fuck 😐 But I was freaking out and being very cautious, checking my socks and body every ten minutes. I tried my best to ignore them before heading to bed by hugging my bf acting like it wasn't bothering me but i kept thinking about them biting my ass. Anyways, hes tired so hes like, "lets sleep" but I tell him no and that I'm just going to sit and stay awake till my sister picks me up. I really did not want to touch his bed b/c I caught like 15 fleas near his bed (his bed is literally a mattress on the floor btw). So he's like, "ok, i wanted to sleep with you though" and just leaves me alone with a disappointed expression. Then Im like, "okay nvm ill sleep next to you if I wear two layers of socks, long pants, and a long shirt. So I do and I sleep but keep waking up randomly to check for fleas. (this method was kind of helpful for preventing the fleas from smelling me and touching me btw)

When I wake up Wednesday morning, I notice some fleas on the bed and kill them and then I notice two black dots on my face and its fucking fleas sucking my face (⊙ˍ⊙). I freak out and then go back to my "safe place" aka the chair and try to sleep there but my arm keeps getting the pins and needles shit cause the desk is hard af. So then Im literally just sitting there waiting for my sister to pick me up at 11:45 am in the morning. Its like 11 and I decide to shower and on my way to the shower, there some fleas grabbing onto my socks... Anyways, I'm showering the best I can b/c I do not want to bring fleas to my house and cause an infestation in my house (three dogs and two family members at home). I come out of the shower as carefully as I can and I look down on my feet and theres a fucking flea that already starts sucking on my toe the second I walk out. I kill that mofo and then wear the clothes I wore when I came to his house (I changed into home clothes when I came to his house). I call him while hes sleeping and ask him to get my two zip lock bags so that I can walk on his carpet to leave his house and maybe not get any fleas on me. He does and then I get some tape to close the holes and hes just staring at me like "what are you doing?". I tell him that I'm trying to prevent fleas from coming with me. Hes like giving me a disappointed look... Then my sis comes and he doesn't tell me good bye so I literally walk back to the bathroom, where he is cleaning my flea infested clothes, and i tell him "you're not going to say good bye????". Then he says he will and does. I ask him if hes mad at me before I walk out and he says a little. Then I ask him why and he thinks for like 10 seconds and just says, "You're too much." and then says to not talk to him right now and to just go. He texts me right after and says he doesn't understand me and why I'm overreacting.

I'm itching as I write this. Yesterday, he texts me that he does not want to talk to me till Friday and to not expect a text till then like I did something wrong? I was really sorry at first like maybe I made him feel uncomfortable in his house by reacting the way I did to this situation or because before I left I asked him if he can handle the fleas in my clothes but shouldn't someone want to help their guest clean their clothes if they got fleas from their home? My boyfriend is not scared of insects by the way and even asked me why I am so fearful of them. Although fleas aren't so scary, I feel like he should be able to understand why I don't want to be around them so I'm not sure why he's mad at me. He even asked me why I don't want to bring a single flea in my home when I've dealt with bugs in my house before but I told him that don't want an infestation in my own house before I left his house. I offered to help him with his situation but he told me he doesn't care about fixing it because the fleas never bothered him to the point he never noticed and because hes moving in a month. I don't understand why he doesn't understand why I'm so disgusted and scared of fleas. I literally found one on my dog today although I tried to be careful. He's usually not like this but he really doesn't understand my hatred for insects. Was I overreacting?

Tl;dr My boyfriend who is not scared of bugs doesn't understand why I'm scared of the fleas in his flea infested house and thinks I'm overreacting.
