My wife [28F] has grown distant after getting promoted

My wife and I have been married for 3 years and together for 6. We share a 2 year old kid. She was working as a teacher at a middle school while I was working as an accountant at a big firm.<br><br> amateurs she recently got a promotion at her job which has caused her to work extra hours every day. Before the promotion, she used to come home from work at around 3:30-4 (we both don't get home at the same time due to different work schedules).<br><br>Despite the recent promotion, her new working hours haven't changed but she was given a lot more responsibilities. So she stays after 4 to do some of the work she couldn't finish and get things done. She usually gets home at around 6:30-7 pm.<br><br>After coming home, she spends time with our kid, plays with him, feeds him and puts him to bed.<br><br>The problem is that once our kid is asleep, she almost always goes to bed immediately. Sometimes she passes out while putting our kid to bed itself.<br><br>We used to spend time together after our kid went to bed. We would talk for hours, have some wine, do "married couple stuff" or watch a movie. But now she doesn't do any of this. Anything that requires her spending time with me, she refuses to do it.<br><br>Everytime I ask her if she could spend some time with me, she says that she is too tired and needs to sleep. I understand that, I really do. I know she might be tired but it doesn't mean that she has to act cold towards me. I feel very lonely whenever she does this. I've asked her to go out to eat or just go out for a walk but she says she's too tired to do it. <br><br>Considering that she is tired, I suggested that she could take the day off but she didn't want to. I asked if she needed help with anything but she declined it. I asked if there was a problem with our relationship and she said that there isn't any.<br><br>I'm going crazy over here. I don't know what to do. She doesn't spend any time with me anymore. The last time we went out was on our anniversary which was on June.<br><br>How do I make her talk about this? What do I say to make her tell me wtf is going on? I'm going crazy. I'm seriously considering a divorce. I know it's not the correct solution but I just want my wife back.<br><br>**TL;DR:** My wife recently got a promotion at her job which has caused her to work extra hours. Due to this, she stays at work longer and when she comes home, she spends timings with our kid and goes to bed immediately after. She doesn't want to spend any time with me and always seems tired. I want to know what's wrong with her but idk what to say to make her talk.
