Be honest/Long rant

My fiance and I lack in communication. I'm getting really tired. I think a lot of times I overreact. But lately he's been going to help his family. Which I don't agree right now because of covid and cases keep going up where we all live. But he will never say no to his family. The day before he left to help, I got sick and we have a 10 month old. He said he wouldn't be gone all day(we share a car). So he left at 6 am and I needed medicine because I wasn't getting any better. He only spoke to me once and didn't respond to my text or phone call. He came back late at night. I just asked if he has even 30 seconds to just shoot me a text. The next week, he leaves again with the car and says he won't be gone all day and he left all day without letting me know that its taking longer . Idk I just wanted one text because he said he'd help me with something when he got back. So I ended up doing it myself. Tomorrow I had to return something by a certain time and he knew that (maybe he forgot) and is deciding to take his family to the airport . Which I dont care because he can go help his family. But he just tells me and it isn't his fault because they just asked him (they have been knowing about this situation) and I just said ok at first but then he says and I'm not going to discuss this with you. So then I had to say that it bothers me because all I want is to be heard and acknowledged and maybe here and there an update. I used to not care but after having a baby. I just feel differently . Anyways, please be honest and let me know what to do. Its probably a feeling a frustration because we just don't communicate well in general and it's just taken a toll on our relationship. I've been trying and have changed so much and sometimes I don't see it being reciprocated
