How long is too long for the silent treatment from your husband?

My husband hasn’t spoken to me (other than a few words here and there bc of baby) since last Thursday. (We did have sex yesterday but then said he was too tired to talk). Every big argument we have he doesn’t deal with the issue straight away or at least before we go to sleep for the day. I hate it. I’m the type of person that overthinks and it’s really affected how I view our marriage. Whether if I’m in the wrong or not, it’s always me having to ask to have the conversation to deal with it and sort through our issues. He likes to call it “nagging” when I do. The last few months I’ve come to realise that I deserve better in that sense and no longer spend my nights crying as to why he isn’t trying to fix it with me. Is this normal for your husband to not talk for this long? BACKSTORY as to why he’s angry: so I posted in here about a gym crush of mine that somehow found my Insta and added me. I wasn’t going to accept but I ended up accepting and following back two days later. I felt awkward at gym when gym guy was looking at me and I didn’t have the balls to say I was married (we literally have only small talked once before this). My profile clearly shows I’m “happily” married and just had a baby. Thankfully, he has had a look at my page and no longer gives me the same attention maybe out of respect. So on Thursday I was in the sauna and didn’t look at my phone. My husband was going off asking why I made my Insta account public, calling me a hoe asking why I have been posting lots lately etc., asking if I made my account for ppl to find me. He went through my follow list and told me to unfollow the gym guy. I follow over 800+ ppl so not sure how he saw who I followed. But I literally follow so many girls & only a few guys from my gym and random other gyms because of the same interest etc. ANYWAYS. he goes off accusing me of cheating, tells me I’m an attention seeking hoe amongst other things. I get home and he’s thrown tables upside down and has smashed vases and a few mirrors. I’ve always used Insta like this, and my husband once did too. He still follows a few random girls from his old gym but rarely follows anyone new but expects me to do the same. Most of the ppl I follow is because we share the same interest and I’ve seen them before. This gym guy was the first guy I have followed back where I was flattered by his attention. My husband doesn’t know that though, and I have unfollowed. This whole thing is messy and I’m not sure what to do. Thank you if you’ve read this far. Yes I probably should have not followed gym guy back, but I really didn’t want to tell him I’m not interested and married especially if I got the vibe completely wrong. But to my husband that is only part of the issue. He is very insecure and jealous and is constantly jealous of any men that I interact with. Even men from our community group. I almost feel anxiety to speak to any males or watch my smiling just in case my husband takes it the wrong way. I used to be very smiley when I speak but now I rarely do. Part of me feels trapped the other part wants to talk to him about this and fix it. I’m just exhausted from constantly being the one to muster the strength to talk about our issues. We’ve not yet been married for 2 years yet and I already feel so deflated. We have a 6 month baby too and I’m put off of having another baby with him if I’m honest 😢
