26m, had kid with wife who is 26f, when does the relationship recover?

So for context, wife and I have been together since 2018. Met when I was in the Marine Corps. I got out in 2021 and she had joined the Navy and is currently on the last year of her contract. Getting out of the Marine corps, I definitely changed and began to see the world for what it was. Discovered a lot of reality shattering things and changed quite a bit as a person. Wife has since changed quite a bit since joining as well. Desensitized, not as romantic, and frankly more lazy(lacks effort in most departments. Our relationship had some up’s and down’s the past 3-4years and we were in a good place about 2 years ago when she got on anti anxiety medication. So much so we decided we wanted to have a kid. We were in a good enough spot financially that we knew we got afford him and man am I glad we did. Greatest thing to ever happen to me. However, during pregnancy she got off her anti anxiety meds and is currently still off them while breastfeeding. Plans to get back on them in 3months when she stops breastfeeding but honestly that seems like forever with how things have been. The first 6months there was a lot of rage and aggression from her, and I was frankly trying to survive so I wasn’t exactly the nicest. Lot of name calling on both parts and got slightly physical on her end. Last 3 months have gotten slightly better when we were on the brink of divorce and relized neither of us wanted that. I feel like we both have quite a bit of resentment towards each other. I mainly do because her anxiety is so bad that she won’t allow me to parent without interjecting or telling me what to do/what i’m doing wrong. Loses control when I don’t do exactly what she says. Trying to be understanding since i know her hormones are still messed up but the resentment continues to build. We got a pretty easy baby and even with teething, we are still getting decent sleep so sleep deprivation isn’t a huge reason. We don’t talk anymore. Not really any conversation unless it’s about our Son. I’ve been trying to give effort towards our relationship. Buying her flowers, taking us out for lunch, selling some investments to get her a kitchenaid mixer since she’s getting into cake baking/decorating. However the effort isn’t reciprocated. Just goes on her phone to watch tiktoks or watches her shows. Feels like we’re roommates and we both have that feeling (it’s been discussed). We start marriage counseling this week but I wanted to ask, when does it eventually get better?
