Pregnant and alone.How can I let my husband do his thing in peace?

Am I going crazy?

Hi everybody

It's my 1st time posting here.First time pregnant, Im in my 3rd tri and I generally feel alone, abandoned and like I'm wasting my time.This is because I kinda started doubting my partner during my pregnancy. So here it goes: - Before I got pregnant, we used to work day and night shifts, so we wouldn't spend time together at all. We were pretty independent. However, we used to say that it would be lovely for me to have some time off, for us to be able to bond, and enjoy each other more - Since I got pregnant, I am basically home all the time( I thought it was gonna be our happiest, most relaxed period as a couple), unless I go visit my family. I took my role as a wife seriously and I am taking care of myself properly, cooking everyday, taking care of the house - my partner is working 2 jobs and recently has started going to the gym; when he gets home, he's tired but he still tries to make me happy, however we either watch TV together or he sits on his phone while I try to talk to him about my day; he said that's normal since we run out of topics to talk about, or if our conversation is dry; I've been trying to crack jokes but he doesn't laugh so I gave up on that; I'm pretty low energy in the evenings when he comes home, too - he's kinda treating me like a chore, like he does me a favor for spending time with me - in my first tri, I discovered that swimming is really relaxing my body, helping me with aches and swelling, and I asked him if we could go swimming together during my pregnancy.We went twice. And I felt lowkey betrayed when he started going to the gym everyday, because obviously I can't go there and I can't go swimming alone either.I understand that it's good for his health, but right now it's just more time for me to be alone. Also, we used to say that when I would get pregnant, we both could get fat together, and then go to the gym when I recover. I guess I'm the only one who remembers this. I still cook high protein meals for him so he can gain weights; - He also follows gym babes a lot on social media, and I'm kinda insecure about it, since I am no longer fit or slim; basically I don't feel he's attractive to me anymore - He usually takes longer to respond to my messages but he's online active on social media which makes me even more anxious - I was the only one who took initiative when buying things for the baby, I literally bought everything and paid alone for my medical check ups 9 times outta 10, he still buys food, house expenses and gym supplies but the fact that he never bought anything for the baby scares me - I tried talking to him about all of this and he either tells me that I'm a drama queen, that I'm overreacting, that I fucked up his day, that there always has to be something with me, I told him once that I feel alone and I would like to spend more time together and he threatened me to leave for the whole day, the whole night and show me how that actually feels, and I ended up having a panic attack, or he generally advices me to just go wherever I want instead of waiting for him, but I physically can't take long walks and I don't feel safe just being outside by myself ; - I need comfort and stability during my pregnancy and all these sudden changes in his schedule and attitude give me really really bad vibes

So I'm focusing more on myself and my pregnancy but deep down Im really disappointed by the way things have turned out between us. Moving further, I'd like to maintain my peace and become better for me and my baby. I definitely don't want to rely on my husband, ask him for things or depend on him with anything.Any suggestions ? Thank you .
