Butt hurt

I feel like I’m being ridiculous for caring, but I’m pregnant and legitimately offended. I think it might be the hormones. I have an awkward relationship with my brother in law, we are both hard to get to know and so we are very quiet towards each other, even though we’ve known each other for 5 years at this point. But the other day I was left alone in the kitchen with him and panicked and just started making small talk and for some reason I was just like “I can’t believe you’ll be 30 soon!” Like totally just blurted it out without thinking. Wondering if he would talk about any upcoming birthday plans, have anything else to say, etc. Anyway he got super awkward and I felt so bad because I guess he’s feeling weird about turning 30, which I should have thought about prior to my word vomit. So fast forward a week, and I was on the phone with my sister in law just talking and I had a flashback to how awkward the exchange with my BIL was and I was like “omg I think I offended ______ the other day I felt so bad.” And I told her what I said and his reaction. And she was like “oh yeah it’s not a big deal that shouldn’t be offensive, don’t worry about it. He did say though, ‘I may be turning 30, but she (meaning me) has 3 kids... so...” and I’m super offended he said that! Is that just me taking it as an insult when he maybe didn’t mean it to be insulting? Or is that my insecurity coming out about having 3 kids already when I’m only 25? I am gonna feel weird around him now and I’m trying not to read into it so I don’t overreact and get upset for no reason lol
